2651-85-6 Usage
Uses
Used in Polymer and Resin Industry:
DIETHYL ETHYLPHOSPHONITE is used as a flame retardant and plasticizer for enhancing the flexibility and flame resistance of polymers and resins. Its incorporation into these materials helps to improve their performance characteristics, making them more suitable for specific applications where flame retardancy and flexibility are required.
Used in Agricultural Chemical Production:
DIETHYL ETHYLPHOSPHONITE serves as a chemical intermediate in the manufacturing process of various agricultural chemicals, including pesticides and herbicides. Its reactivity and phosphorus content make it a valuable component in the synthesis of these compounds, contributing to their effectiveness in controlling pests and unwanted plant growth.
Used in Chemical Warfare:
Although its use is highly regulated and monitored under the Chemical Weapons Convention, DIETHYL ETHYLPHOSPHONITE is recognized as a potential chemical warfare agent. Its potential toxicity and ability to cause harm if ingested, inhaled, or absorbed through the skin highlight the need for strict control and safety measures in its production, handling, and storage.
Check Digit Verification of cas no
The CAS Registry Mumber 2651-85-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2651-85:
(6*2)+(5*6)+(4*5)+(3*1)+(2*8)+(1*5)=86
86 % 10 = 6
So 2651-85-6 is a valid CAS Registry Number.

A convenient and simple one-pot method is described for the synthesis of phosphonites [RP(OEt)2, 1] and H-phosphinates [HP(O)R(OEt), 2] from triethyl phosphite and appropriate Grignard reagents.
Autoxidation of Ethyl Phosphinite, Phosphonite, and Phosphite Esters
Hwang, Wen-Shu,Yoke, John T.
, p. 2088 - 2091 (2007/10/02)
The AIBN-initiated autoxidations in benzene of triethyl phosphite P(OEt)3, diethyl ethylphosphonite, EtP(OEt)2, and ethyl diethylphosphinite, Et2POEt, were studied at 50 deg C.The quantitative conversion of P(OEt)3 to triethyl phosphate obeys the rate law rate = (2.0 x 1E-4 atm-1s-1)PO2 and is zero order in phosphite.Autoxidation of EtP(OEt)2 and Et2POEt gives the complete mixture of intermediates and products predicted by Buckler's mechanism for the autoxidation of trialkylphosphines.At 1 atm of oxygen pressure and 0.02 M AIBN the pseudo-first-order rate law is rate = k', with k'= 7.49 x 1E-4 s-1 for EtP(OEt)2 and 2.37 x 1E-4 s-1 for Et2POEt.
