29800-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29800-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,8,0 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 29800-93:
129 % 10 = 9
So 29800-93-9 is a valid CAS Registry Number.

Kinetic Study of the Reduction of Trimethyl Phosphate, Triethyl Phosphate, and Tributyl Phosphate by Sodium in Liquid Ammonia

Isbell, D. C.,Dewald, R. R.

, p. 6695 - 6698 (2007/10/02)

The reactions of trimethyl phosphate, triethyl phosphate, and tributyl phosphate with sodium in liquid ammonia were found to be consistent with second-order kinetics, first order with respect to the ammoniated electron and first order with respect to the trialkyl phosphate.One mole of the trialkyl phosphate was found to react with two moles of sodium to yield the alkoxide and dialkyl phosphite.The second-order rate constant for trimethyl phosphate at -34 deg C was found to be (1.8+/-0.1)*103 M-1 s-1.The second-order rate constants for triethyl phosphate and tributyl phosphate were determined at various temperatures.Activation energies of 5.6+/-0.2 and 7.6+/-0.2 kcal/mol were calculated for triethyl phosphate and tributyl phosphate, respectively.A mechanism in which the rate-determining step is the cleavage of an alkoxy group is suggested.
