69861-02-5 Usage

Uses

This monomer is commonly used in the formulation of research silicone hydrogel contact lenses and other research ophthalmic devices. Silicone monomers are preferred for the synthesis of research ophthalmic materials due to their high oxygen permeability.

Check Digit Verification of cas no

The CAS Registry Mumber 69861-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,6 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 69861-02:
(7*6)+(6*9)+(5*8)+(4*6)+(3*1)+(2*0)+(1*2)=165
165 % 10 = 5
So 69861-02-5 is a valid CAS Registry Number.

Preparation method of organosilicon monomer compound

-

Paragraph 0046; 0051-0053; 0056, (2021/04/28)

The invention relates to a preparation method of an organosilicon monomer compound. According to the preparation method, allyl glycidyl ether is used as a raw material and subjected to epoxy ring-opening substitution, hydrosilylation and a substitution esterification reaction to obtain the target compound. The method comprises the following steps: (1) subjecting an initial raw material to reacting with an alkali metal halide under the condition of a phase transfer catalyst to obtain an intermediate beta-halohydrin; (2) carrying out addition on the intermediate beta-halohydrin and bis(trimethylsiloxy)methylsilane under the catalysis of chloroplatinic acid to obtain an intermediate II; and (3) substituting the intermediate II with methacrylate to obtain a final compound. According to the above reaction synthesis route, generation of a large number of isomers in an existing method can be avoided, production of impurities is avoided in the aspect of reaction route design, and then, high-purity monomer is obtained.

SILICONE COMPOUND PRODUCTION METHOD

-

Paragraph 0035-0040, (2021/10/13)

PROBLEM TO BE SOLVED: To provide a polymerizable group-containing silicone monomer production method for realizing a high-purity silicone monomer by inhibiting generation of silylation products of impurities in a reaction stage of synthesis. SOLUTION: The production method comprises reacting an epoxy-containing organopolysiloxane represented by the general formula (1) in the figure (n is an integer from 1 to 10, and A is a siloxanyl group) with an acrylic or methacrylic acid in the presence of a transition metal Lewis acid.
