632-79-1 Usage

Chemical Properties

white to light yellow powder

Uses

Different sources of media describe the Uses of 632-79-1 differently. You can refer to the following data:
1. Tetrabromophthalic Anhydride is a brominated flame retardant used as additives in plastics to decrease the rate of combustion of these materials, leading to greater consumer safety.
2. tetrabromophthalic anhydride is a reactive flame retardant, can be used for polyester resin, epoxy resin, flame retardant, also can be used for flame retardant for PS, PP, PE, flame-retardant ABS resin.

General Description

Pale yellow crystalline solid.

Air & Water Reactions

Insoluble in water. Sensitive to moisture .

Reactivity Profile

Tetrabromophthalic anhydride reacts exothermically with water. This reaction is expected to be slow, but can become vigorous if local heating accelerates it. Reaction with water is accelerated by acids. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.

Fire Hazard

Flash point data for Tetrabromophthalic anhydride are not available. Tetrabromophthalic anhydride is probably combustible.

Check Digit Verification of cas no

The CAS Registry Mumber 632-79-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 632-79:
(5*6)+(4*3)+(3*2)+(2*7)+(1*9)=71
71 % 10 = 1
So 632-79-1 is a valid CAS Registry Number.

Synthesis method of 4-halogenated phthalic anhydride and derivative thereof

-

Paragraph 0024; 0028-0029; 0033-0034; 0038-0039; 0043-0044;, (2020/12/30)

The invention relates to a synthetic method of 4-halogenated phthalic anhydride and a derivative of the 4-halogenated phthalic anhydride, and solves the technical problems of low product purity, poorproduct performance, complex synthetic process and low utilization ratio of monohalide isomers and polyhalides in the existing production process. The method specifically comprises the following steps: dissolving phthalic anhydride in an organic solvent, and introducing a halogenating reagent under the action of iron powder and a Lewis acid catalyst to prepare a halogenated phthalic anhydride mixture; rectifying and purifying the polyhalogenated phthalic anhydride mixture to obtain a 4-halogenated phthalic anhydride pure product; and continuing subjecting residual halogenated phthalic anhydride mixture to halogenation reaction under the action of fuming sulfuric acid and the catalyst to prepare tetrahalogenated phthalic anhydride, and to realize comprehensive utilization of the raw materials. The method is widely applied to the technical field of flame retardant synthesis.

Intermediates to tetrabromophthalic anhydride and process therefor

-

, (2008/06/13)

Tetrabromophthalic anhydride and the corresponding free acid are propared by oxidizing in the liquid phase a compound of the formula STR1 each of A and A' is independently selected from oxygen, OH or acetoxy; each of R and R' is independently selected from H, OH, alkyl, alkylidene or oxygen; x is 0 or 1; y is 3-x; and Ry and R'y may together form a closed alicyclic or heterocyclic ring structure. Mixtures of two or more compounds of formula (I), optionally in the presence of an oxidation catalyst, can also be employed as the starting material.

Halogenated polyol-ester neutralization agent

-

, (2008/06/13)

Haze-free reactive flame retardant halo polyols are made by reacting (a) a halogen containing cyclic acid anhydride (e.g. tetrabromophthalic anhydride), (b) an aliphatic polyol, e.g. diethylene glycol, and (c) an epoxide, e.g. propylene oxide, and including potassium salt of fatty acids (e.g. potassium acetate) in the reaction mixture in an amount at least sufficient to neutralize residual sulfuric acid that is usually present in the halogen containing cyclic acid anhydride.
