20.11 DECARBOXYLATION OF CARBOXYLIC ACIDS

20.11 DECARBOXYLATION OF CARBOXYLIC ACIDS 977 This reaction, which also does not occur in base, bears a close resemblance to the decarboxy-lation of b-keto acids because both malonic acids and b-keto acids have a carbonyl group bto the carboxy group. Because decarboxylation of malonic acid and its derivatives requires heating, the acids

Decarbing Cannabis - B/R Instrument

Decarboxylation, also known as decarbing, is the process of converting cannabinoid acids to their corresponding cannabinoids. THCA, CBDA, CBGA, and others undergo a chemical reaction that produce THC, CBD and CBG. Decarboxylation occurs most often due to heat. In the process, a molecule of carbon dioxide is released causing a small loss of weight.
