IUPAC - NIST Solubility Data Series 66. Ammonium Phosphates Jitka Eysseltova´ Charles University, Prague, Czech Republic Thedford P. Dirkse Calvin College, 3201 Burton Street, SE, Grand Rapids, Michigan 49546 Received January 1, 1997; revised manuscript received October 26, 1998 The solubility of ammonium phosphate is reviewed. Many ammonium phosphates can be described in terms of the ternary system: NH3 –PO5–H2O. However, this system differs from systems like the sulfates and halates in that it has a marked tendency to form condensed oligophosphate ions. The literature survey covers the period up to 1988. © 1998 American Institute of Physics and American Chemical Society. @S0047-2689~98!00406-1# Key words: ammonium compounds; aqueous solutions; solubility; phosphates.

In this letter, we provide a mechanochemical method of inorganic magnesium and calcium salt−urea ionic cocrystal synthesis to obtain enhanced stability nitrogen fertilizers. The solvent-free mechanochemical synthesis presented can result in a greater manufacturing process sustainability by reducing or eliminating the need for solution handling and evaporation. NH3 emission testing suggests that urea ionic cocrystals are capable of decreasing NH3 emissions to the environment when compared to pure urea, thus providing implications for a sustainable global solution to the management of the nitrogen cycle.

  • Mechanochemical Catalytic Transfer Hydrogenation of Aromatic Nitro Derivatives
    Article Mechanochemical Catalytic Transfer Hydrogenation of Aromatic Nitro Derivatives Tomislav Portada, Davor Margetić and Vjekoslav Štrukil * Division of Organic Chemistry and Biochemistry, Ruđer Bošković Institute, Bijenička cesta 54, 10000 Zagreb, Croatia; [email protected] (T.P.); [email protected] (D.M.) * Correspondence: [email protected]; Tel.: +385‐1‐468‐0197 Received: 15 November 2018; Accepted: 29 November 2018; Published: date Abstract: Mechanochemical ball milling catalytic transfer hydrogenation (CTH) of aromatic nitro compounds using readily available and cheap ammonium formate as the hydrogen source is demonstrated as a simple, facile and clean approach for the synthesis of substituted anilines and selected pharmaceutically relevant compounds. The scope of mechanochemical CTH is broad, as the reduction conditions tolerate various functionalities, for example nitro, amino, hydroxy, carbonyl, amide, urea, amino acid and heterocyclic. The presented methodology was also successfully integrated with other types of chemical reactions previously carried out mechanochemically, such as amide bond formation by coupling amines with acyl chlorides or anhydrides and click‐type coupling reactions between amines and iso(thio)cyanates. In this way, we showed that active pharmaceutical ingredients Procainamide and Paracetamol could be synthesized from the respective nitro‐precursors on milligram and gram scale in excellent isolated yields. Keywords: mechanochemistry; catalytic transfer hydrogenation; aromatic nitro derivatives; ammonium formate; aging; ball milling; synthesis 1. Introduction Catalytic hydrogenation is one of the most significant functional group transformation reactions in organic synthesis and numerous procedures and reagents have been developed for that purpose [1,2]. As such, the hydrogenation reaction plays one of the key roles in many industrially important processes, for example hydrogenation of carbon monoxide to methanol or in food industry for the conversion of unsaturated vegetable oils into saturated triglycerides [3].

The pKa shifts can be quite significant adjusting pH in reversed phase liquid chromatography (RPLC), in the high organic environment used for HILIC. For example, especially when using mass spectrometric (MS) detection. This weak bases with aqueous pKa less than ~4 typically will not be practice has been carried over to hydrophilic interaction liquid protonated in HILIC mobile phases when 0.1 v/v % formic acid chromatography (HILIC) separations. However, the mechanisms is used. The pKa of the base is decreased in HILIC mobile phase of action and the relative importance of buffer cation and while the pKa of the formic acid is increased. The increased pKa anion are much different in HILIC than RPLC. For this reason of formic acid leads to an increase in mobile phase pH.

    SIAM 24, 17-20 April 2007 US/ICCA SIDS INITIAL ASSESSMENT PROFILE CAS Nos. 7722-76-1, 7783-28-0, 68333-79-9, 8011-76-5, 65996-95-4 Phosphate category: Monoammonium phosphate (MAP), Chemical Names Diammonium phosphate (DAP), Ammonium polyphosphate (APP), Single superphosphate (SSP), Triple superphosphate (TSP) MAP: NH4H2PO4 DAP: (NH4)2HPO4 Structural Formula APP: SSP: main components:Ca(H2PO4)2. H2O /CaSO4.H2O TSP: CaHPO4.2H2O SUMMARY CONCLUSIONS OF THE SIAR Category/Analogue Rationale The category consists of monoammonium phosphate (MAP; CAS No. 7722-76-1), diammonium phosphate (DAP; CAS No. 7783-28-0), ammonium polyphosphate (APP; CAS No. 68333-79-9), single superphosphate (SSP; CAS No. 8011-76-5), and triple superphosphate (TSP; CAS No. 65996-95-4). All members of the category are mainly or exclusively used as fertilizer and have one common functional group (phosphate) that equilibrates between several different ionic species - = = -3 [H3PO4, H2PO4 , HPO4 , HPO4 , or PO4 ] depending on the pH of the environment. Thus, chemical reactions for all compounds in this category are similar with the exception of the actual dissociation product, which forms calcium or ammonia along with common phosphate moieties. However, the presence of the ammonium ion will influence the observed toxicity and its data are used to conservatively represent the toxicity of the category members. Under typical environmental conditions, the phosphate would be present as monohydrogen = - - phosphate (HPO4 ) or dihydrogen phosphate (H2PO4 ) with the equilibrium favoring H2PO4 as the acidity of the environment increases. Under these conditions, the proportions of phosphoric acid -3 (H3PO4) and the phosphate anion (PO4 ) would be extremely low.

  • Prohibited and Restricted Chemical List
    School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only.
