| titleOfInvention | A method for purifying 2-amino-N- (1-methylethyl) benzamide |
| abstract | The solution relates to the cleaning method 2-n-amino-N- (1-methylethyl) benzamide for the purpose ofnremoval of impurities, which are acidic substances,nof a basic and neutral nature. The essence of the waynCleaning consists in being rawn2-Amino-N- (1-methylethyl) benzamide dissolvednin water or organic solvents, heatednaromatic hydrocarbonsnsuch as benzene, toluene, xylene, ethers such as diethyl ether,n1,2-dimethoxyethane, halogenated hydrocarbonsnas dichloromethane, 1,2-dichloroethane,nchloroform, esters of acetic acid at room temperaturenboiling of the solvent was treated with 1 to 6 N aqueousna solution of basic agents such as carbonates,nalkali hydrogen carbonates and hydroxidesnmetals and alkaline earth metals up tonneutral reaction after separation of aqueous solutionsnof basic agents to the organic phasenwith activated charcoal at 0.2 to 3%nwt. to the weight of the crude product at temperaturenboiling of the solvent, insoluble matternfiltered and the filtrate cooled to room temperaturen0 to 10 ° C, optionally concentrated to crystallization. |
