Manufacturing Process
To a mixture of 7.5 parts by weight of 1,2,4-triethoxybenzene, 40 parts by
volume of tetrachloroethane and 7.5 parts by weight of succinic anhydride are
added 23 parts by weight of anhydrous aluminum chloride. The mixture is
stirred for 1 hour at 25°C and for another 2 hours at 60°C. After addition of
50 parts by weight of ice and 50 parts by volume of concentrated hydrochloric
acid, the reaction mixture is subjected to steam distillation.
After cooling crystals separated from the remaining liquid are collected by
filtration and recrystallized from aqueous ethanol, whereby 2.5 parts by
weight of 3-(2',4',5'-triethoxybenzoyl)-propionic acid are obtained as colorless
needles, melting point 150°C to 151°C.

Check Digit Verification of cas no
The CAS Registry Mumber 41826-92-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,2 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41826-92:
(7*4)+(6*1)+(5*8)+(4*2)+(3*6)+(2*9)+(1*2)=120
120 % 10 = 0
So 41826-92-0 is a valid CAS Registry Number.

The present invention provides a cement admixture that comprises at least one of a carboxylic acid based copolymer comprising a reactive surfactant as a monomer or a copolymer salt obtained by neutralizing the copolymer with an alkaline substance, a method for preparing the same, and a cement composition comprising the same. The cement admixture of the present invention increases composition fluidity even at a high water-reducing formulation by improving dispersibility of cement particles, prevents a decrease of fluidity as the function of time, and offers good workability by supplying an adequate amount of air flow continuously.
