Environmental Fate
Soil. Hydrolyzes rapidly in soil forming fenoxaprop acid, ethyl alcohol, 6-chloro-2,3dihydrobenzoxazole-2-one and 4-(6-chloro-2-benzoxazolyloxy) phenol (Wink and Luley, 1988; Humburg et al., 1989). Under aerobic and anaerobic conditions, the half-life was less than 24 hours (Humburg et al., 1989).Plant. The major degradation product identified in crabgrass, oats and wheat was 6chloro-2,3-dihydrobenzoxazol (Lefsrud and Hall, 1989).Photolytic. Susceptible to degradation by UV light (Humburg et al., 1989).

Check Digit Verification of cas no
The CAS Registry Mumber 66441-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,4 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66441-23:
(7*6)+(6*6)+(5*4)+(4*4)+(3*1)+(2*2)+(1*3)=124
124 % 10 = 4
So 66441-23-4 is a valid CAS Registry Number.

High-efficiency low-pollution fenoxaprop-p-ethyl production process
-
, (2021/07/31)
The invention discloses a high-efficiency and low-pollution production process of fenoxaprop-p-ethyl. The production process comprises the following specific steps: (1) preparing fenoxaprop-p-ethyl; S1, preparing sulfydryl-6-chlorobenzoxazole; S2, preparing 2,6-dichlorobenzoxazole; and S3, synthesizing the fenoxaprop-p-ethyl. According to the fenoxaprop-p-ethyl, fenoxaprop-p-ethyl is finally synthesized through preparation of sulfydryl-6-chlorobenzoxazole and preparation of 2,6-dichlorobenzoxazole, the technology is simple, operation is convenient, efficiency is high, the speed is high, the production cost is saved, the income is increased, and filter residues generated in the production process can be safely treated through the technology; the waste gas enters a waste gas treatment facility for treatment and is discharged after reaching the standard; and the wastewater is desalted, removed salt is washed and dried by methanol to serve as a byproduct, and evaporated condensate water enters a factory sewage treatment station to be treated, so that the aim of protecting the environment is fulfilled, and the functions of high efficiency and low pollution are achieved.
