BLUESTEIN, ALBERT HYBL* AND YosHIMI AL NISHIOKA INTRODUCTION The reaction kinetics of the alcoholysis of substituted benzoyl chlorides was studied. The mechanism of the alcoholysis reaction, which is most generally accepted ( 1), shows that the overall re­ action should be second-order and that the reaction should be first-order with respect to the acid chloride and first-order with respect to the alcohol. This rate study was carried out using a large excess of alcohol as the solvent, thus obtaining pseudo-first order rate constants, first-order with respect to the acid chloride only.

  • Surface Modifications of Poly(Ether Ether Ketone) Via Polymerization
    materials Review Surface Modifications of Poly(Ether Ether Ketone) via Polymerization Methods—Current Status and Future Prospects Monika Flejszar and Paweł Chmielarz * Department of Physical Chemistry, Faculty of Chemistry, Rzeszow University of Technology, Al. Powsta´nców Warszawy 6, 35-959 Rzeszów, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-17-865-1809 Received: 24 January 2020; Accepted: 20 February 2020; Published: 23 February 2020 Abstract: Surface modification of poly(ether ether ketone) (PEEK) aimed at applying it as a bone implant material aroused the unflagging interest of the research community. In view of the development of implantology and the growing demand for new biomaterials, increasing biocompatibility and improving osseointegration are becoming the primary goals of PEEK surface modifications. The main aim of this review is to summarize the use of polymerization methods and various monomers applied for surface modification of PEEK to increase its bioactivity, which is a critical factor for successful applications of biomedical materials. In addition, the future directions of PEEK surface modifications are suggested, pointing to low-ppm surface-initiated atom transfer radical polymerization (SI-ATRP) as a method with unexplored capacity for flat surface modifications. Keywords: PEEK; surface modification; polymer brushes; ultraviolet (UV)-initiated graft polymerization; SI-ATRP 1. Introduction Currently, the production of bone implants is limited only to metal materials (stainless steel, cobalt–chromium, titanium). However, in the production of personalized bone implants, there is an alternative synthetic polymer named poly(ether ether ketone) (PEEK) [1–3]. The chemical structure of PEEK can be defined as an alternating combination of aryl rings through ketone and ether groups; therefore, it belongs to the family of polyaryletherketone polymers.

  • Grignard Reaction: Synthesis of Triphenylmethanol
    *NOTE: Grignard reactions are very moisture sensitive, so all the glassware in the reaction (excluding the work-up) should be dried in an oven with a temperature of > 100oC overnight. The following items require oven drying. They should be placed in a 150mL beaker, all labeled with a permanent marker. 1. 5mL conical vial (AKA: Distillation receiver). 2. Magnetic spin vane. 3. Claisen head. 4. Three Pasteur pipettes. 5. Two 1-dram vials (Caps EXCLUDED). 6. One 2-dram vial (Caps EXCLUDED). 7. Glass stirring rod 8. Adaptor (19/22.14/20) Grignard Reaction: Synthesis of Triphenylmethanol Pre-Lab: In the “equations” section, besides the main equations, also: 1) draw the equation for the production of the byproduct, Biphenyl. 2) what other byproduct might occur in the reaction? Why? In the “observation” section, draw data tables in the corresponding places, each with 2 columns -- one for “prediction” (by answering the following questions) and one for actual drops or observation. 1) How many drops of bromobenzene should you add? 2) How many drops of ether will you add to flask 2? 3) 100 µL is approximately how many drops? 4) What are the four signs of a chemical reaction? (Think back to Chem. 110) 5) How do the signs of a chemical reaction apply to this lab? The Grignard reaction is a useful synthetic procedure for forming new carbon- carbon bonds. This organometallic chemical reaction involves alkyl- or aryl-magnesium halides, known as Grignard 1 reagents. Grignard reagents are formed via the action of an alkyl or aryl halide on magnesium metal.

Received: 17 November 2017; Accepted: 4 December 2017; Published: 7 December 2017 Abstract: The synthesis of different photo-reactive poly(alkenyl norbornenes) and poly(oxonorbornenes) containing benzophenone (BP) via ring-opening metatheses polymerization (ROMP) is described. These polymers are UV irradiated to form well-defined surface-attached polymer networks and hydrogels. The relative propensity of the polymers to cross-link is evaluated by studying their gel content and its dependency on BP content, irradiation wavelength (254 or 365 nm) and energy dose applied (up to 11 J·cm−2). Analysis of the UV spectra of the polymer networks demonstrates that the poly(oxonorbornenes) show the expected BP-induced crosslinking behavior at 365 nm, although high irradiation energy doses and BP content are needed. However, these polymers undergo chain scission at 254 nm. The poly(alkenyl norbornenes), on the other hand, do not cross-link at 365 nm, whereas moderate to good cross-linking is observed at 254 nm. UV spectra demonstrate that the cross-linking at 254 nm is due to BP cross-linking combined with a [2 + 2] cylcoaddition of the alkenyl double bonds.

  • Friedel and Crafts' Reaction-The Preparation of Orthobenzoyl-Benzoic Acid and Benzophenone
    732 C. R. RUBIDGE AND N. C. QUA. two and five-tenths grams of cyanimidocaxbonic ethyl ester, prepared from bromocyanogen, potassium cyanide, and alcohol1 were added to the suspended alcoholate. Heat was developed, the solution became yellow, and sodium cyanide was precipitated. The reaction mixture was heated for two hours in a flask connected with a reflux condenser, and enough water was added to dissolve the sodium cyanide. After the water solution had been extracted with ether several times, the ether was dried with calcium chloride. Thus, 32 g. of a light yellow oil, possessing a strong basic odor, were obtained when the ether was evaporated. Even at a pressure of 25 mm. the compound could not be distilled without consid- erable decomposition. Therefore, no analysis of the substance was at- tempted. Its identity was established by converting it into the corre- sponding oximido derivative. Preqaration of Oximidocarbonic Ethyl Isoamyl Ester, CZHS@-C~C~HII,- II NOH Eight and four-tenths grams of hydroxylamine, dissolved in a small amount of water, were added to 20 g. of the imido ester dissolved'in 20 cc. of ether.

    criteria for a recommended standard. OCCUPATIONAL EXPOSURE TO BENZOYL PEROXIDE U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health Ju n e 1977 For sate by the Superintendent of Documents,Government U.S. Printing Office, Washington, D.C. 20402 DHEW (NIOSH) Publication No. 77-166 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and safety of workers exposed to an ever-increasing number of potential hazards at their workplace. The National Institute for Occupational Safety and Health has projected a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the health effects of exposure. The Secretary of Labor will weigh these recommendations along with other considerations such as feasibility and means of implementation in developing regulatory standards.
