Performing reactions including organic reactants is a tuff job. Organic compounds should be handled carefully and proper reaction conditions must be given to yield the perfect products. Answer and Explanation:1 Reflux is a special method used in practical organic chemistry to heat the reactants dur...
Application transformation of methyl glycinate Add an appropriate amount of methyl glycinate, 5 equivalents of HCOOH and 3 equivalents of HCHO to a round-bottomed flask, heat the reaction mixture to reflux, and maintain the reflux state for 24 hours. After the reaction is completed, the mixture ...
35 parts of hexamethylene bis-dicyandiamide, 35 parts of p-chloroaniline hydrochloride and 250 parts of β-etoxyethanol are stirred together at 130- 140°C for 2 hours under reflux. The mixture is then cooled and filtered. The solid is washed with water and crystallised from 50% aqueous acet...
Medications for obesity are being discussed now more than ever it seems. And with good right: Just as people with diabetes and depression can find relief from their medical conditions via pharmaceutical assistance, so, too, can people with obesity.
