General Description

2-ethyl-2-[[[[(3-isocyanato-4-methylphenyl)amino]carbonyl]oxy]methyl]propylene (3-isocyanato-4-methylphenyl)carbamate is a chemical compound with the formula C15H18N2O4. It is a carbamate compound, containing an isocyanate functional group bonded to a phenyl ring. This chemical is often used as a crosslinking agent in the production of polyurethane and other polymers, where it helps to improve the strength and durability of the material. It is also used as a raw material in the production of various industrial products, such as adhesives, coatings, and foams. However, exposure to this chemical can be hazardous to human health if not handled properly, and appropriate safety measures should be taken when working with it.

Check Digit Verification of cas no

The CAS Registry Mumber 1431-54-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1431-54:
(6*1)+(5*4)+(4*3)+(3*1)+(2*5)+(1*4)=55
55 % 10 = 5
So 1431-54-5 is a valid CAS Registry Number.

A 65/35 toluene diisocyanate synthetic 75% solid content, method for preparing low-free curing agent

-

Paragraph 0042; 0043; 0044; 0045; 0046; 0047; 0048-0051, (2016/10/08)

The invention relates to a method for preparing a low-free curing agent with the solid content of 75% by synthesis of 65/35 toluene diisocynate (TDI). The method is characterized by comprising the following steps of: (1) reacting the TDI with trimethylolpropane (TMP) in a reaction solvent at 70+/-5 DEG C to obtain a prepolymer; (2) adding 2,4,6-tris(dimethylaminomethyl)phenol, namely a trimerization catalyst, to the prepolymer when the weight percentage of a free NCO group is detected to be 15%-16%, and adding phosphoric acid, namely a trimerization inhibitor, to the prepolymer for stopping reaction when the weight percentage of the free NCO group is reduced to 14%-15%; and (3) after 2, 6-butylated hydroxytoluene, namely an antioxidant, is added, diluting a prepolymer by a general solvent for polyisocyanates to discharge when a prepolymer curing agent is changed into transparent liquid, when the complete reaction is finished within 2.5h-4h. The obtained environmental-friendly coating curing agent with low-free TDI and high solid content has the excellent characteristics of high gloss of a coating film as well as high elasticity and toughness, and greatly reduces toxicity and transportation costs.
