Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
45 words
A process for preparing oxime containing silicon compounds which comprises reacting an oxime with a silicon compound having at least three nitrogen atoms linked to the same silicon atom of said compound through Si--N bonding at a temperature of from about 0° to 150° C.
Claim 2
Dependent Claim
45 words
A process for preparing oxime containing silicon compounds which comprises reacting an oxime with a silicon compound having at least three nitrogen atoms linked to the same silicon atom of said compound through Si--N bonding at a temperature of from about 0° to 150° C.
Claim 3
Dependent Claim
29 words
The process of claim 1, wherein the oxime is reacted with the silicon compound in a ratio of one mol of oxime for each gram atom of Si-bonded nitrogen.
Claim 4
Dependent Claim
19 words
The process of claim 1, wherein the reaction is conducted at a temperature of from 15° to 50° C.
Claim 5
Dependent Claim
74 words
The process of claim 1, wherein the oxime has the formula HON═X, in which X is selected from the group consisting of CRR 1 and CR 2 , R is selected from the group consisting of monovalent hydrocarbon radicals and substituted monovalent hydrocarbon radicals, R 1 is selected from the group consisting of hydrogen and R, and R 2 is selected from the group consisting of bivalent hydrocarbon radicals and substituted bivalent hydrocarbon radicals.
Claim 6
Dependent Claim
50 words
The process of claim 1, wherein the silicon compound has the formula R.sub.a Si(NR.sub.2.sup.1).sub.4-a, in which R is selected from the group consisting of monovalent hydrocarbon radicals and substituted monovalent hydrocarbon radicals, R 1 is selected from the group consisting of hydrogen and R and a is 0 or 1.
