Air & Water Reactions
Water soluble.
Reactivity Profile
An organo-isocyanate. Isocyanates and thioisocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide.
Fire Hazard
Flash point data for 1,3,5-Tris(2-hydroxyethyl)cyanuric acid are not available, but 1,3,5-Tris(2-hydroxyethyl)cyanuric acid is probably combustible.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 839-90-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 839-90:
(5*8)+(4*3)+(3*9)+(2*9)+(1*0)=97
97 % 10 = 7
So 839-90-7 is a valid CAS Registry Number.

Paragraph 0041-0067, (2021/02/10)
The invention relates to the field of organic chemical industry, in particular to a preparation method of tris (2-hydroxyethyl) isocyanurate. According to the method, a chloroethanol route is used, iodide ions are used as a catalyst, a proper feeding mode and a purification method are adopted, and the defects that the method is complex in process, long in reaction period and inconvenient in excessive recovery of chloroethanol are overcome. Iodine ions are used as a catalyst so that the temperature during the reaction of chloroethanol and cyanuric acid is reduced. Meanwhile, the equivalent chloroethanol is added in a dropwise adding manner so that the self reaction of the chloroethanol and the generation of impurities generated by the reaction of the theic and the chloroethanol are reduced,the operation is simple, the purification is convenient, and the industrial prospect is better.
Application of the study of reactivity of alkaline salts of isocyanuric acid to the synthesis of mono and trisubstituted isocyanurates
Chiron-Charrier,Caubere
, p. 2659 - 2672 (2007/10/02)
Reactivity of alkaline salts of isocyanuric acid has been studied. It has been established that the nucleophilic substitution is not selective because of the protonic exchanges between salts and substituted derivatives. The synthesis of mono or trisubstituted derivative is due to secondary reactions and to solvent effects. With this study, it has been possible to settle a method to prepare mono and trisubstituted derivatives of isocyanuric acid.
