Sodium methyl sulfate is commonly employed as a methylating agent.

Check Digit Verification of cas no

The CAS Registry Mumber 512-42-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 512-42:
(5*5)+(4*1)+(3*2)+(2*4)+(1*2)=45
45 % 10 = 5
So 512-42-5 is a valid CAS Registry Number.

Preparation method of 4-methylanisole

-

Paragraph 0041-0043; 0044-0047; 0052-0058, (2019/08/20)

The invention discloses a preparation method of 4-methylanisole. The method includes: using p-cresol and sodium hydroxide as the raw materials to prepare p-methylphenol sodium; allowing the p-methylphenol sodium and dimethyl sulfate to have methylation in a nonpolar solvent to prepare the 4-methylanisole and byproduct sodium methylsulfate; allowing the p-methylphenol sodium and the byproduct sodium methylsulfate to have reaction in a polar solvent to prepare the 4-methylanisole and sodium sulfate. The method has the advantages that the 4-methylanisole is prepared through the three-step reaction, the utilization rate of the dimethyl sulfate is increased, and wastewater zero discharge is achieved.
