Toluene 2,5-diisocyanate (TDI) is an organic compound widely used in the production of polyurethane foams, elastomers, and coatings. It is a colorless, toxic liquid with a pungent odor and is classified as an aromatic diisocyanate. TDI is formed by the reaction of toluene diamines with phosgene, and it exists in two isomers: 2,4-TDI and 2,6-TDI. Due to its high reactivity, TDI can cause severe health issues, including respiratory problems, skin irritation, and potential carcinogenic effects. As a result, it is crucial to handle TDI with proper safety measures and personal protective equipment.

614-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 614-90-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 614-90:
(5*6)+(4*1)+(3*4)+(2*9)+(1*0)=64
64 % 10 = 4
So 614-90-4 is a valid CAS Registry Number.

Process for the production of the toluene diisocyanate

-

Page/Page column 5; 6, (2008/06/13)

The invention relates to a process for the production of toluene diisocyanate, in which the crude toluenediamine obtained from the hydrogenation is purified and then phosgenated. The purification step reduces the total amount of cyclic ketones to less than 0.1 % by weight, based on 100% by weight of the toluenediamine.
