Abstract
At the stage of acetonization of L-sorbose in neutralization of the acid reaction mass in the production of ascorbic acid, one of the most important qualitative indices of the process is the alkali concentration in the solution of diacetone-L-sorbose (I), the content of which is regulated in the range 1-8 g/liter. A more alkaline medium causes condensation of acetone to mesitylene oxide, which makes the quality of the regenerated acetone poorer and ultimately affects the yield of the end product. Acid medium causes decomposition of I [I].
