1087-21-4 Usage
Preparation
Diallyl isophthalate (DAIP) is prepared by esterification of isophthalic acid
with allyl alcohol:
The polymers of diallyl isophthalate are very similar in preparation,
properties and application to the polymers of diallyl phthalate described
above. Mouldings based on diallyl isophthalate are more expensive but have
enhanced thermal stability (withstanding up to about 220°C for long periods)
and resistance to organic solvents.

Check Digit Verification of cas no
The CAS Registry Mumber 1087-21-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,8 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1087-21:
(6*1)+(5*0)+(4*8)+(3*7)+(2*2)+(1*1)=64
64 % 10 = 4
So 1087-21-4 is a valid CAS Registry Number.

Manufacture of chloromethyl-substituted polyfluoroalkyl esters
-
, (2008/06/13)
Compounds having the formula: STR1 wherein Rf is perfluorinated saturated aliphatic containing 3-20 carbons; R1 is optionally substituted alkyl, aryl, aralkyl or cycloalkyl; and n is a number from 1 to 4. Process for preparing compounds (I): STR2 The reaction can be carried out, e.g., by melting an iodine-substituted polyfluoroalkyl ester and contacting the molten ester with chlorine, or an iodine-substituted polyfluoroalkyl ester can be suspended or dissolved in a suitable liquid and reacted with chlorine. A suitable liquid is inert under the reaction conditions; e.g. alcohols or water should be avoided. Process of using compounds (I) to treat (a) textile materials so as to give them dry soil resistance and oil and water repellency, and (b) paper so as to make it repel water and oil.
