22719-43-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22719-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,7,1 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22719-43:
(7*2)+(6*2)+(5*7)+(4*1)+(3*9)+(2*4)+(1*3)=103
103 % 10 = 3
So 22719-43-3 is a valid CAS Registry Number.

Temperature and Pressure Effects on the Reversible Reaction of a Parent Phenol (GH) Corresponding to Galvinoxyl with Aliphatic Amines

Nishimura, Norio,Iga, Siroh,Satoh, Masahiro,Yamamoto, Shunzo

, p. 2437 - 2441 (2007/10/02)

The effects of temperature and pressure on the reversible reaction between GH and aliphatic amines in acetonitrile have been studied spectrophotometrically.The formation of the free ions rather than that of ion pairs has been confirmed by the modified Benesi-Hildebrand (B-H) plot.From the plot the equilibrium constants were estimated.From the temperature dependence of the equilibrium constant (K), the heat and entropy of reactions were estimated to be: (ΔH0)av=-44.5 kJ mol-1, and (ΔS0)av=-193 J K-1 mol-1.From the pressure dependence of K the reaction volume (ΔV0)av was estimated to be -40 dm3 mol-1.When unbranched primary amines were used, a side reaction took place for which an explanation has been given.
