Snyder et al. [94] compared supercritical extraction with classical sonication and Soxhlet extraction for the extraction of selected organophosphorus insecticides from soil. Samples extracted with supercritical carbon dioxide modified with 3% methanol at 350atm and 50°C gave a =85% recovery of Diazinon (diethyl-2-isopropyl-6-methyl-4-pyrimidinyl phosphorothiodate or 0,0 diethyl-0-(2-isopropyl-6-methyl-4-pyrimidyl) phosphorothioate). Ronnel (or Fenchlorphos) 0,0-dimethyl-0-2,4,5 trichlorophenol phosphorothiodate), Parathion ethyl (diethyl-p-nitrophenyl (phosphorothioate), Tetrachlorovinphos (trans,-2-chloro-l-(2,4,5 trichlorophenyl) vinyl (chlorophenyl-O-methylphenyl phosphorothioate) and Methiadathion. Supercritical fluid extraction with methanol modified carbon dioxide has been applied to the determination of organophosphorus insecticides in soil [260].

O-p-Nitrophenyl phosphorothioate is at best a poor substrate. Breslow and Katz (111) gave a VmM for O-p-nitrophenyl phosphorothioate (pH 8.0, 1.0 M NaCl, 25°C), which is 100 times smaller than for p-... 

In contrast to the above, Neumann 109), using an enzyme solution (pH 8.7, 0.1 M tris, 25°C) 3000 times more concentrated than that of Breslow and Katz, did not detect hydrolysis of O-p-nitrophenyl phosphorothioate after 2 hr. She also reported the isolation of an extremely stable enzyme-nitrophenyl phosphorothioate complex. One might speculate that in the light of the extreme stability of the proposed enzyme-phosphorothioate complex, the complex may actually be a covalent species...

The thio analogue of paraoxon, diethyl-p-nitrophenyl phosphorothioate (parathion, 17), is practically more adequate because of its lower toxicity to warmblooded animals and higher stability against hydrolysis. It was prepared by Schrader in 1944, and the elucidation of its biological properties was due to Kiikenthal and Unterstenhofer (Schrader and Kukenthal, 1948 Unterstenhofer, 1948 Schrader, 1952b). 

Based on the process developed by Schrader (1948c), its production began in 1949. It is 2-3 times more sensitive to hydrolysis than parathion. In a manner similar to parathion, it undergoes thion-thiol isomerisation at high temperatures. However, isomerisation results in different products. While 0,0-diethyl-S-p-nitrophenyl phosphorothioate (25) is formed from parathion, the isomerisation of parathion-methyl under identical conditions yields 0,S-dimethyl-0-(p-nitro-phenyl) phosphorothioate (26) (McPherson and Johnson, 1956).
