Abstract
A melamine skeleton-bearing organosilicon compound has a film forming ability, water solubility and compatibility with resins. It is prepared by reacting cyanuric chloride with a primary and/or secondary amine compound and neutralizing with a base.
Claims4
A method for preparing an organosilicon compound of formula (1):
- wherein R0 is independently hydrogen or a substituted or unsubstituted monovalent hydrocarbon radical which may be separated by carbonyl carbon or a heteroatom selected from the group consisting of oxygen, sulfur and nitrogen, and at least one of R0 is the following structure (A):
- wherein the broken line designates a valence bond, X is a substituted or unsubstituted divalent hydrocarbon radical which may be separated by carbonyl carbon or a heteroatom selected from the group consisting of oxygen, sulfur, and nitrogen, the divalent hydrocarbon radical bonding to the nitrogen atom via a carbon atom at one end and bonding to the silicon atom via a carbon atom at the other end, R1 is independently hydrogen or a substituted or unsubstituted C1-C4 alkyl radical, R2 is independently a substituted or unsubstituted C1-C4 alkyl radical, and n is an integer of 1 to 3, said method comprising
- reacting cyanuric chloride with a primary and/or secondary amine compound, said primary and/or secondary amine compound comprising either an organosilicon compound having the general formula (3):
- wherein X is a substituted or unsubstituted divalent hydrocarbon radical which may be separated by carbonyl carbon or a heteroatom selected from the group consisting of oxygen, sulfur, and nitrogen, the divalent hydrocarbon radical bonding to the nitrogen atom via a carbon atom at one end and bonding to the silicon atom via a carbon atom at the other end, R1 is independently hydrogen or a substituted or unsubstituted C1-C4 alkyl radical, R2 is independently a substituted or unsubstituted C1-C4 alkyl radical, R3 is independently hydrogen or a substituted or unsubstituted monovalent hydrocarbon radical which may be separated by carbonyl carbon or a heteroatom selected from the group consisting of oxygen, sulfur, and nitrogen, and n is an integer of 1 to 3, or the organosilicon compound of formula (3) together with another reactant having a primary and/or secondary amino radical, and
- neutralizing with ethylenediamine.
