Glycerine derivatives represented by formula (1A), (2A) and (3A):
wherein R1a, R2a, R1b, R2b, R1c, and R2c are as defined in the disclosure, and process for producing glycerin derivatives, including the glycerin derivatives (1A), (2A) and (3A), are disclosed. The glycerin derivatives have satisfactory physical properties and are applicable as lubricants or polar oils and also have mutual effects with water and are applicable as emulsifying agents or moisture retaining agents. The process makes it possible to synthesize glycerin derivatives from easily and economically available aldehydes or ketones in high yields.

A liquid phase hydrogenolysis of acetal compounds such as cyclic acetals and cyclic ketals are fed to a reaction zone and reacted in the presence of a noble metal catalyst supported on a carbon or silica support to make hydroxy ether mono-hydrocarbons in high selectivity, without the necessity to use acidic co-catalysts such as phosphorus containing acids or stabilizers such as hydroquinone.

Catalyst compositions of palladium supported on alumina or zirconium oxide supports having low or no silicon dioxide contents and having a specific surface area or modified with alkali, alkaline earth, or phosphine oxide compounds are selective in a vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products.

A vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products using a supported noble metal catalyst. The hydrogenolysis reaction can be carried out in the vapor phase and in the absence of a polyhydroxyl hydrocarbon co-solvent.
