Phenol, 2,2'-ethylidenebis[4,6-dimethyl-], also known as Bisphenol A (BPA), is an organic compound with the chemical formula C15H16O2. It is a white crystalline solid that is primarily used in the production of polycarbonate plastics and epoxy resins. BPA is a key component in the manufacturing of various consumer products, such as food and beverage containers, dental sealants, and thermal paper receipts. However, it has been a subject of concern due to its potential endocrine-disrupting properties and health risks associated with long-term exposure, leading to restrictions and alternatives in certain applications.

3772-19-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3772-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,7 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3772-19:
(6*3)+(5*7)+(4*7)+(3*2)+(2*1)+(1*9)=98
98 % 10 = 8
So 3772-19-8 is a valid CAS Registry Number.

Lignin-based diphenylmethane diisocyanate as well as preparation method and application thereof

-

Paragraph 0093-0096; 0133-0136, (2021/11/21)

The invention discloses a lignin-based diphenylmethane diisocyanate and a preparation method and application thereof. As shown in Formula I, the lignin-based diphenylmethane diisocyanate is prepared by reacting a lignin-cracking monomer compound II with a carbonyl compound to give compound III, compound III reacts with chloroacetyl ammonia to obtain compound IV, compound IV is subjected Smiles rearrangement reaction to obtain compound V, and compound V is reacted with a compound containing carbon-containing acid to obtain the lignin-based diphenylmethane diisocyanate shown in formula I. The product replaces MDI for synthesis of polyurethane materials, and the toughness of the polyurethane material is improved. Thermal stability and glass transition temperature. When being applied to polyurethane waterproof coating, the water absorption rate is obviously reduced, and the stability of the coating is improved.
