77813-84-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77813-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,1 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77813-84:
(7*7)+(6*7)+(5*8)+(4*1)+(3*3)+(2*8)+(1*4)=164
164 % 10 = 4
So 77813-84-4 is a valid CAS Registry Number.

PHENOLIC EPOXY COMPOUNDS

-

Paragraph 0075-0076, (2016/02/03)

Disclosed herein are compositions and methods of making phenolic compounds, and resins comprising these phenolic compounds. The compounds include multifunctional epoxies, amino glycidyl derivatives, and multi-functional amines prepared from hydroxymethyl derivatives of phenols and bisphenols.

Epoxidizable fatty amide-phenol conjugates

Zerkowski, Jonathan A.,Haas, Michael J.

, p. 1229 - 1237 (2011/11/14)

This paper reports the synthesis of a series of novel compounds where carboxylic acids have been linked to a phenol through amidomethyl units. For instance, one, two, or three fatty acids have been selectively appended to the phenol in yields above 75%. The fatty acid used was oleic acid, which was subsequently epoxidized. Other functional groups, such as amino acids, can be incorporated in these compounds. Examples of monomers that are suitable for polymerization were also prepared: one acrylamide, one styrene derivative, and two types of AB2 diamino acids, all of which contain oleic units that are sites for epoxidation and crosslinking. Fatty acid aryl ethers were prepared using hydroxy fatty acids. These molecules are intended to serve as augmented analogues of epoxidized vegetable oil. Their amide groups should lead to intermolecular aggregation through hydrogen bonding, and the option to covalently include other functional groups may permit tuning of the macroscopic materials properties of films, coatings, or solids constructed from them.
