General Description

3-Chloro-4-methylbenzenesulfonic acid is a chemical compound with the molecular formula C7H7ClO3S. It is a sulfonic acid derivative of toluene, with a chlorine atom and a methyl group substituted on the benzene ring. 3-CHLORO-4-METHYLBENZENESULFONIC ACID is primarily used as a building block in the production of various pharmaceuticals and agrochemicals. It is also used as an intermediate in the synthesis of dyes, pigments, and other specialty chemicals. 3-Chloro-4-methylbenzenesulfonic acid is a white crystalline solid that is soluble in water and organic solvents. It is important to handle this chemical with caution, as it may cause irritation to the skin, eyes, and respiratory system.

Check Digit Verification of cas no

The CAS Registry Mumber 98-34-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98-34:
(4*9)+(3*8)+(2*3)+(1*4)=70
70 % 10 = 0
So 98-34-0 is a valid CAS Registry Number.

Method for achieving pipe-type continuous production of CLT acid nitride

-

, (2016/11/17)

The invention discloses a method for achieving pipe-type continuous production of CLT acid nitride. The method comprises the steps that 1, methylbenzene and sulfuric acid conduct a sulfonation reaction in a sulfonation pipe reactor; 2, thth sulfonation reaction solution obtained in the first step and chlorine are continuously fed into a chlorination pipe reactor for a chlorination reaction; 3, the chlorination reaction solution obtained in the second step and nitric acid are continuously fed into a nitrification pipe reactor for a nitrification reaction, and then the CLT acid nitride is prepared. According to the method for achieving pipe-type continuous production of the CLT acid nitride, purification treatment does not need to be conducted on an intermediate in the reaction process, operation is easy, the reaction efficiency is high, and the objective product selectivity is high.

Highly selective oxidative monochlorination to synthesize organic intermediates: 2-Chlorotoluene, 2-chloroaniline, 2-chlorophenol, and 2-chloro-4-methylphenol

, p. 196 - 200 (2013/09/08)

An alternative manufacturing process scheme was developed to synthesize monochloro-substituted aromatic compounds in high selectivity, involving oxidalive chlorination by using HCI-H2O2. Thus, 2-chlorotoluene, 2-chloroaniline, and 2-chlorophenol were synthesized by oxidative chlorination followed by desulphonation or decarboxylation. Oxidative chlorination of 4-methylbenzenesulphonic acid, 4-methylbenzoic acid, 4-aminobenzoic acid, and 4-hydroxybenzoic acid by using a suitable ratio of reactantr:HCI:H2O2, and their subsequent desulphonation or decarboxylation, gave 60-85% yield of the desired products. Oxidative chlorination of 4-methylphenol by using HCI-H2O2 gave as high as 98% selectivity to the desired 2-chloro-4-methylphenol.
