FREMGANGSMAADE TIL FREMSTILLING AF ORGANISKE DERIVATER AF LERMINERALER SAMT FREMGANGSMAADE TIL FJERNELSE AF SIMPLE OG KOMPLEKSE METALLISKE AN- OG KATIONER FRA VANDIGE OPLOESNINGER

摘要

In a method for preparing a pillared, reactive and cross-linkable organo- derivative of clay mineral, the mineral is dispersed in water and is then mixed with an organic compound having up to about 10 carbon atoms and having the structure R1-ORGANYL-R2 wherein the organyl group is a hydrocarbyl group, R1 is a salt-forming group that in the salt form bears a positive charge, R2 is either a salt-forming group that in the salt form bears a positive charge or a salt-forming group that in the salt form bears a negative charge, R1 and R2 being separated by at least two carbon atoms. The resultant mixture is maintained at a temperature of 25 DEG C to 150 DEG C for 0.1 to 24 hours to produce the required pillared material.
