, p. 64 - 65 (1989)
Sodium periodate/wet silica gel in the presence of dichloromethane is an efficient reagent for the oxidative cleavage of 1,2-diols and the oxidation of hydroquinones.This easily prepared reagent provides a good alternative of classical metaperiodate oxidation, especially for the preparation of aldehydes, which easily form hydrates.

Paragraph 0028-0043, (2018/09/13)
The invention discloses a method for green, efficient and selective synthesis of chlorphenesin. Glycerol and 4-chlorophenol directly serve as raw materials, diethyl carbonate serves as a selective synthesis agent, separate synthesis can be performed in situ, orientation reaction is ensured, other by-products are omitted, separation and purification are simple, yield is 95% under proper conditions,and purity is 99.5% or more. The yield of the chlorphenesin is greatly improved, high-toxic and expensive 3-chlorine-1, 2-propanediol is abandoned by the aid of low-cost and non-toxic glycerin, reaction conditions are mild, and industrial production is facilitated.

Paragraph 0082; 0083, (2017/09/01)
The invention relates to a synthetic method of chlorobenzene glyceryl ether. 3-chloro-1,2-propanediol and parachlorophenol are directly used as raw materials, high-corrosion chemical solvents are not introduced, a reaction is simple, the yield is high, and the yield can reach 95 percent or more under the optimal reaction condition. By adding a few phase transfer catalysts, the reaction can be promoted to be conducted quickly and effectively, and the reaction time can be shortened by at least two hours.
