Nonflammable

Check Digit Verification of cas no

The CAS Registry Mumber 27955-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,5 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27955-94:
(7*2)+(6*7)+(5*9)+(4*5)+(3*5)+(2*9)+(1*4)=158
158 % 10 = 8
So 27955-94-8 is a valid CAS Registry Number.

Synthesis and characterization of new aromatic polyesters derived from new aromatic di- and tri hydroxyl monomers with 4-phenylenediacrylic acid and malonic acid

Mutar, Mohammed A.

, p. 7846 - 7852 (2014)

In the present work, six new aromatic polyesters (PE1-PE6) have been synthesized in high yields from the polycondensation between di- and tri hydroxyl monomers containing methylene unit, Schiff-base linkages and pyridine heterocyclic ring with 4-phenylenediacrylic acid and malonic acid using dibutyltin dilaurate as catalyst. The structure analysis of the polymers has been carried out by using FT-IR and 1H NMR spectroscopy. The monomers were characterized by FTIR and 1H NMR. FT-IR technique confirmed the esterification of di and tri hydroxyl monomers by the acid in all the polymers.

Method for synthesizing and purifying 1,1,1-tri(4-hydroxy phenyl) ethane

-

Paragraph 0021; 0022; 0023; 0024; 0025, (2016/11/17)

The invention discloses a method for synthesizing and purifying 1,1,1-tri(4-hydroxy phenyl) ethane, and belongs to the field of chemical synthesis. According to the method, a 1,1,1-tri(4-hydroxy phenyl) ethane (THPE) crude product is synthesized from phenol and p-hydroxyacetophenone by using hydrochloric acid as a catalyst and zinc chloride as a promoter, and is purified to obtain a pure product having a purity higher than 99 percent. The method is an economical and efficient method for producing the 1,1,1-tri(4-hydroxy phenyl) ethane with high reaction yield, and is also an efficient purification method for improving purity.

supporting information; experimental part, p. 3964 - 3966 (2010/01/06)

The free energy of complexation of supramolecular complexes containing phenol-carbamate H-bonds is an additive function of the number of H-bonds, with a constant increment of 6 kJ mol-1 per interaction in carbon tetrachloride.
