Production process of N-acetylamino gluceo metho aldehyde acetal

Abstract

The invention discloses a producing method of N-acetamino glucose methylal, including: neutralizing amino glucose hydrochloride and agent, obtaining amino glucose, acetylating the amino glucose by acetic anhydride to obtain N-acetamino glucose, making acetalation reaction on the N-acetamino glucose on condition of sulphuric acid and methanol existing, obtaining N-acetamino glucose methylal. It has simple producing method and high purity of product; high yield of product, up to 80% above.

Description

Technical field: [0001] The invention relates to a production method of N-acetylglucosamine methylal. Background technique: [0002] With the development of immunochemistry, scientific research shows that oral administration of N-acetylglucosamine formal can timely regulate the content of N-acetylglucosamine formal in the blood, and transfer it into human cells in time to improve the function of joint tissues. Due to the fast absorption and transformation speed and good taste, it can be fed directly in the microbial fermentation process, which is conducive to increasing the active ingredient content of functional drinks and increasing the curative effect. Therefore, most of the active ingredients of functional drinks developed in domestic and foreign markets, such as immune drinks and in vivo microbial population adjustment drinks, are substitutes for N-acetylglucosamine methylal. [0003] The existing production method of N-acetylglucosamine methylal has complicated proces...
