32687-77-7 Usage

General Description

3-(3,5-Di-tert-butyl-4-hydroxyphenyl)propanohydrazide is a chemical compound with antioxidant properties commonly used in the manufacturing of polymers, plastics, and rubber products to protect them from degradation caused by heat, light, and oxygen exposure. It is a derivative of 3,5-di-tert-butyl-4-hydroxyphenylpropanoic acid and has the potential to inhibit the oxidation of various organic substances. The compound is also used as a stabilizer in the production of adhesives, coatings, and sealants, and it can be found in some cosmetic and personal care products. Additionally, its antioxidant properties make it a potentially beneficial ingredient in the field of pharmaceuticals and food preservation as well.

Check Digit Verification of cas no

The CAS Registry Mumber 32687-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,6,8 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 32687-77:
(7*3)+(6*2)+(5*6)+(4*8)+(3*7)+(2*7)+(1*7)=137
137 % 10 = 7
So 32687-77-7 is a valid CAS Registry Number.

Paragraph 0038; 0039; 0047; 0048; 0056; 0057; 0063; 0064, (2018/09/21)

The invention provides a synthetic method for an organic synthesis antioxidant 1024, that is, a synthetic method for N,N'-bis[beta(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine. The preparation method comprises the following steps: firstly synthesizing beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propanohydrazide by using hydrazine hydrate and beta-(3,5-di-tert-butyl-4-hydroxyphenyl)methyl propionate as raw materials, and synthesizing the N,N'-bis[beta(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine by using the beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propanohydrazide and ethyl acetoacetate as raw materials. According to the method provided by the invention, a solvent type, a mass ratio of one reactant to another reactant and a mass volume ratio of reactants to solvents in a reaction system are adjusted, so that the reaction is performed more thoroughly, a product yield is greatly improved, and the product yield in a pilot plant test can still be guaranteed to be higher than acurrent level.

A method for preparing an antioxidant

Paragraph 0064; 0067-0068, (2018/02/04)

The invention provides a preparation method for an antioxidant. The method includes: subjecting a compound shown as formula (III) and a compound shown s formula (IV) to dehydration reaction in the presence of an organic solvent. The method is characterized in that in the dehydration reaction process, the reaction generated water and part of the organic solvent are separated from the reaction system, and water division treatment is carried out, then the water-containing organic solvent subjected to water division treatment contacts a first dehydrating agent, and the organic solvent obtained after contact is returned to the reaction system. Specifically, n is 1 or 2, x is 1 or 2, y is an integer of 0-6, R1 and R2 are not a straight chain or branched chain alkyl group with a hydrogen atom or carbon atom number of 1-6 at the same time, and R3 and R4 are not a straight chain or branched chain alkyl group with a hydrogen atom or carbon atom number of 1-6 at the same time. By adopting the method provided by the invention to prepare the antioxidant, the dehydration effect of the reaction system can be enhanced, and accordingly the reaction efficiency and product yield can be enhanced. (formula III and formula IV).
