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.
grafting technique. The [SO3H]-SBA-15 catalysts were characterized by nitrogen adsorption at 77 K, X-ray diffraction, SEM and titrations. All the catalysts were active in the studied reaction being the [SO3H]3-SBA-15 the best one. It was observed that the reaction rate increase with the amount of sulfonicacid groups on SBA-15 until a maximum. With high amounts of sulfonic groups, a decrease of activity is
