摘要:
A process for producing a glyceryl ether which contains a markedly small amount of organohalogen compounds and therefore can be used even for cosmetics and body detergents. The process comprises reacting an alcohol with an &agr;-epihalohydrin in the presence of an acid catalyst, subjecting the reaction mixture to ring closure to convert it into the corresponding glycidyl ether and then hydrolyzing the glycidyl ether, wherein: (a) the hydrolysis is effected at 140 to 230° C. in the presence of a salt formed from a strongly basic compound and a weakly acidic compound, or (b) the reaction mixture after the hydrolysis is heated at 100 to 230° C. in the presence of a salt formed from a strongly basic compound and a weakly acidic compound.

摘要:
Ether compounds, which are useful as solvents, cosmetics, detergents, lubricants, emulsifiers and so on, are produced by reacting (a) a hydroxy compound with a carbonyl compound of (b) a carbonyl compound under hydrogen atmosphere in the presence of a catalyst with ease and at a low cost. The reaction is carried out while removing out produced water by using a dehydrating agent during the reaction; by distilling off the water by azeotropic dehydration and the like; or by blowing gases such as hydrogen gas to flow through the reaction system.

摘要:
The present invention relates to a process for producing glycidol from glycerol carbonate as a raw material with a high yield. The process for producing glycidol according to the present invention includes the steps of (1) reducing a content of a salt having a weak acidity in glycerol carbonate to 1500 ppm by mass or less; and (2) obtaining the glycidol from the glycerol carbonate.
摘要:
The present invention relates to a process for producing glycidol from glycerol carbonate by subjecting the glycerol carbonate to decarboxylation reaction in the presence of a solvent containing no active hydrogen. In the process, glycidol can be produced from glycerol carbonate as a raw material of the glycidol with a high selectivity.
