Paragraph 0046; 0047, (2019/09/14)
The invention provides a method for producing camphorquinone by taking a byproduct generated in the camphor synthesis process as a raw material, belonging to the technical field of organic synthesis.The byproduct 3-camphene ester generated in the synthesis process of camphor is used as a starting material to prepare high-purity camphorquinone through refining, saponification, dehydrogenation, condensation, hydrolysis and recrystallization steps. The method has the beneficial effects that the value of the byproduct generated in the camphor synthesis process is used, industrial wastes are reduced, wastes are changed into valuables, environmental pressure is reduced, a brand-new path for the synthesis of the camphorquinone is provided, no heavy metals are used in all process steps, truly nontoxic chemical synthesis of the camphorquinone is realized, and the method is an economic and environment-friendly production process.

CrO3 in CH2Cl2/CH3COOH/(CH3CO)2O oxidizes hydrocarbons to alcohols and ketones, 5α-androstane and 3β-acetoxy-5α-androstane are converted to 5α-androst-14-en-16-ones.
