Uses

Different sources of media describe the Uses of 86-65-7 differently. You can refer to the following data:
1. Azo dye intermediate.
2. 7-Amino-1,3-naphthalenedisulfonic Acid is a reagent which may be used in the preparation of pyrimidine derivatives.

Safety Profile

Questionable carcinogen with experimental neoplastigenic data. When heated to decomposition it emits toxic fumes of NOx and SOx.

Check Digit Verification of cas no

The CAS Registry Mumber 86-65-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 86-65:
(4*8)+(3*6)+(2*6)+(1*5)=67
67 % 10 = 7
So 86-65-7 is a valid CAS Registry Number.

Production method of K acid

-

Paragraph 0024; 0028; 0032; 0036, (2017/07/20)

A production method of a K acid comprises the following steps: 1, mixing 2-naphthol (I) with 92-98% sulfuric acid, introducing a gas, and carrying out a primary sulfonation reaction to obtain a compound (II); 2, reacting the compound (II) with a potassium salt and an ammonium salt, and carrying out an ammonification reaction and sulfuric acid acidifying to obtain a compound (III); and 3, mixing the compound (III) with 95-98% sulfuric acid, introducing a gas, and carrying out a secondary sulfonation reaction to obtain a compound (IV) that is the K acid. The chemical equation of the method is shown in the description. The method effectively increases the utilization rate of sulfuric acid in the sulfonation process, greatly reduces the production amount of waste sulfuric acid and even industrial sulfates, avoids production operating inconvenience brought by use of 20% nicotinic acid and 65% nicotinic acid, improves the operability of the process, and also has the advantages of small sulfuric acid use amount, low production cost, high product quality and small environmental pollution.

-

, (2008/06/13)

The novel triphendioxazine dyestuffs of the formula STR1 in which the substituents R, R', T1, T2, X, Y and n have the meanings given in the description are highly suitable for the dyeing and printing of cellulose-containing or amido-containing material.

Reactive dye having both monochlorotriazinyl and vinylsulfone type reactive groups

-

, (2008/06/13)

A novel reactive monoazo dye, capable of giving cellulose fiber materials a deep orange to scarlet color and superior in build-up and chlorine fastness properties, represented by a free acid of the formula, STR1 wherein R1 is hydrogen, methyl or ethyl; R2 is an alkyl having 1 to 4 carbons that is either unsubstituted or substituted with hydroxy, cyano, alkoxy, halogen, carboxy, alkoxycarbonyl or sulfonic acid; Z is hydrogen or sulfonic acid; A is phenylene and is either unsubstituted or substituted with 1 or 2 substituents selected from the group consisting of methyl, ethyl, methoxy, ethoxy, chlorine, bromine and sulfonic acid, or natphthylene that is either unsubstituted or substituted with sulfonic acid; X is --SO2 CH=CH2 or --SO2 CH2 CH2 Y in which Y is a group that is splittable by alkalis; and m is an integer of 1 to 3.
