Reactions of cycloalkanones or selected heteroaromatics with aldehydes in presence of 10 mol% of various acetates in acetic acid afforded a,a'-bis(substituted-benzylidene)cycloalkanones and substituted-benzyl- idene-mackinazolinones, respectively, in good yields. Among the compounds tested, ammonium acetate is the best and effective especially towards the reactions of mackinazolinone and aliphatic aldehydes to afford 6-alkylidene- mackinazolinones.

    Ammonium Carbamate Hazard Summary Identification

    Common Name: AMMONIUM CARBAMATE CAS Number: 1111-78-0 RTK Substance number: 0091 DOT Number: NA 9083 Date: January 1996 Revision: March 2002 ------------------------------------------------------------------------- ------------------------------------------------------------------------- HAZARD SUMMARY WORKPLACE EXPOSURE LIMITS * Ammonium Carbamate can affect you when breathed in. The following exposure limits are for Ammonia: * Exposure can irritate the skin and eyes causing redness and tearing. OSHA: The legal airborne permissible exposure limit * Breathing Ammonium Carbamate can irritate the nose, (PEL) is 50 ppm averaged over an 8-hour throat and lungs causing coughing and/or shortness of workshift. breath. NIOSH: The recommended airborne exposure limit is IDENTIFICATION 25 ppm averaged over a 10-hour workshift and Ammonium Carbamate is a white crystalline (sand-like) 35 ppm, not to be exceeded during any 15 minute powder. It is used as a fertilizer and ammoniating agent. work period. REASON FOR CITATION ACGIH: The recommended airborne exposure limit is 25 ppm averaged over an 8-hour workshift and * Ammonium Carbamate is on the Hazardous Substance 35 ppm as a STEL (short-term exposure limit).
