1119-73-9 Usage

General Description

2,4-Hexadienedioic acid, (E,Z)-, also known as maleic acid, is a organic compound with the formula C4H4O4. It is a colorless crystalline solid with a pungent odor, and is soluble in water. Maleic acid is commonly used in the production of polyester resins, as well as in the synthesis of other chemical compounds. It is also used as a food additive and in the manufacturing of various consumer products. Maleic acid is considered to be relatively non-toxic, but prolonged or high-level exposure can cause irritation to the skin, eyes, and respiratory system.

Check Digit Verification of cas no

The CAS Registry Mumber 1119-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1119-73:
59 % 10 = 9
So 1119-73-9 is a valid CAS Registry Number.

Cis, cis -Muconic acid isomerization and catalytic conversion to biobased cyclic-C6-1,4-diacid monomers

Carraher, Jack M.,Pfennig, Toni,Rao, Radhika G.,Shanks, Brent H.,Tessonnier, Jean-Philippe

, p. 3042 - 3050 (2017/07/24)

Renewable terephthalic and 1,4-cyclohexanedicarboxylic acids can be produced from biomass via muconic acid using a combination of biological and chemical processes. In this conversion scheme, cis,cis-mucononic acid is first obtained by fermentation using



Page/Page column 32, (2012/06/30)

A method which comprises contacting the cyclohexene ring containing compounds having carboxylate derivatives at the 1 and 4, and optionally the 2, positions with one or more dehydrogeoation catalysts, optionally in the presence of one or more oxidants, in a continuous flow mode under conditions such that compounds containing an aromatic ring with carboxylate derivatives at the 1. and 4 positions, and optionally the 2 position, are prepared. The invention also relates to such compounds derived from starting materials derived from renewable resources.

Synthesis of muconic acids peracetic acid oxidation of catechols

McKague, A. Bruce

, p. 1463 - 1475 (2007/10/03)

Monomeric and dimeric muconic acids were prepared in 30-83% yield by oxidation of catechols with peracetic acid in acetic acid.
