Organophilic clay.

摘要

There are disclosed an organophilic clay which comprises a hydroxypolyoxyethylenealkyl ammonium ion represented by the following formula: wherein R1, R2, R3 and R4 may be the same or different, and each represent a (CH2CH2O)nH group (where n is 2 or more, preferably 2 to 20), a hydrogen atom or an alkyl group having 1 to 30 carbon atoms, provided that one to three of R1 to R4 is/are a (CH2CH2O)nH group(s) and at least three of R1 to R4 are (CH2CH2O)nH group(s) and alkyl group(s), being introduced in interlayers of an expandable layer silicate, a method for preparing the same and a gellant for a high polar organic solvent.
