Abstract

The invention discloses a production process of green and nontoxic sulfobutyl ether-beta-cyclodextrin sodium salt, and particularly relates to the field of sulfobutyl ether-beta-cyclodextrin sodium salt. The process comprises the following steps: S1: providing tetrahydrofuran, acetyl chloride, zinc chloride, a sodium sulfite aqueous solution, beta-cyclodextrin and a sodium hydroxide aqueous solution; S2: preparation of a monomer 4-chloro-butanesulfonic acid: pouring tetrahydrofuran and acetyl chloride into a container, adding zinc chloride to prepare an intermediate product, introducing the intermediate product into a sodium sulfite aqueous solution for full reaction, and carrying out hydrolyzing with hydrochloric acid to obtain the 4-chloro-butanesulfonic acid. According to the invention, tetrahydrofuran and acetyl chloride react to obtain 4-chlorine-butanesulfonic acid, then beta-cyclodextrin and 4-chlorine-butanesulfonic acid serve as raw materials and are added into a container to react, and compared with the method that 1, 4-butanesultone with toxicity serves as a preparation raw material, the process is more environmentally friendly and free of toxicity, and improves certain safety.

Description

technical field [0001] The invention relates to the field of sulfobutyl ether-β-cyclodextrin sodium salt, and more particularly, the invention relates to a production process of green nontoxic sulfobutyl ether-β-cyclodextrin sodium salt. Background technique [0002] Sulfobutyl ether-β-cyclodextrin sodium is a new type of anionic high water-soluble cyclodextrin derivative, which can be well included with drug molecules to form non-covalent complexes, thereby improving the stability and water-solubility of drugs. , safety, reduce nephrotoxicity, ease drug hemolysis, control drug release rate, mask bad odor, etc. Compared with β-cyclodextrin, it has better water solubility, less hemolysis and low nephrotoxicity, and is a new type of pharmaceutical excipient with very broad application prospects; [0003] Relevant patent one: CN103694376B, it adopts two steps, namely synthesis reaction: temperature control 20-30 ℃, add organic solvent and the sodium hydroxide aqueous solution ...
