The degradation of (Z)- and (E)-1,3-dichloropropenes and 1,2-dichloropropane in soil

The degradation of (Z)- and (E)-1,3-dichloropropenes and 1,2-dichloropropane in soil. Roberts, Terry R.; Stoydin, George (Woodstock Lab., Shell Res. Ltd., Sittingbourne, Engl.). Pestic. Sci., 7(4), 325-35 (English) 1976. CODEN: PSSCBG. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) In sealed glass containers, (Z)- [10061-01-5] and (E)-1,3-dichloropropene [10061-02-6] were converted in soil into the corresponding 3-chloroallyl alcs., which were in part strongly bound to the soil. (Z)- [1609-93-4] and (E)-3-chloroacrylic acid [2345-61-1] were also formed as minor products. Other polar products were detected which released the chloroacrylic acids in 20-30% yield upon hydrolysis. The 1,3-dichloropropenes were degraded to the same products in soil in open glass jars outside, although volatilization of the pesticides occurred.There are some commonly used reagents with their cas registry numbers 4643-06-5 and 1609-93-4 in this article. 14C-labeled 1,2-dichloropropane (I) [78-87-5] was only slightly degraded in soil in closed containers, and after 10 days storage of I-treated soil in the open, <1% of the original label remained owing to volatilization of I. Potatoes grown in soil 6 months after treatment with a mixt. of radiolabeled 1,3-dichloropropenes and I contained only 0.007 mg pesticide residue/kg, although 5% of the applied radiolabel was present in the soil at harvest. .

DOCUMENT TYPE: Journal CA Section: 80 (Organic Analytical Chemistry) Section cross-reference(s): 5, 19 Methods for the detn. of cis- and trans- isomers of 3-chloro-allyl alc. (CAAL) and 3-chloroacrylic acid (CAAC) in water and soil were developed. Both CAAL and CAAC were identified as major degradates of the soil fumigant, 1,3-dichloropropene (1,3-D). The methods required derivatization prior to quantitation by gas chromatog. with mass spectrometric detection (GC/MS). CAAL residues were converted to the corresponding cis- and trans-3-chloroallyl isoBu carbonates using isoBu chloroformate. CAAC residues were converted to the corresponding cis- and trans-3-chloroacrylic acid t-butyldimethylsilyl esters using N-methyl-N-(t-butyldimethylsilyl)trifluoroacetamide (MTBSTFA). The GC/MS used electron impact ionization with selected ion monitoring (SIM) of two electron impact ionization with selected ion monitoring (SIM) of two ions for each analyte. Recoveries for CAAL in surface water fortified at the 0.1 ng/mL level averaged 83% with a std. deviation (SD) of 7% for both the cis- and trans- isomers. Recoveries for CAAL in soil fortified at the 0.4 ng/g level averaged 88% with a SD of 10% for the cis- and 90% with a SD of 9% for the trans- isomers. Calcd. limits of detection (LOD) for each CAAL isomer in surface water and soil were 0.02 ng/mL and 0.1 ng/g, resp. Recoveries for CAAC in surface water fortified at the 0.05 ng/mL level averaged 89 and 90%, each with a SD of 6%, for the cis- and trans- isomers, resp. Recoveries for CAAC in soil fortified at the 0.2 ng/g level averaged 83% with a SD of 11% for the cis = and 87% with a SD of 9% of the trans- isomers. Calcd. LOD's for each CAAC isomer in surface water and soil were 0.009 ng/mL and 0.06 ng/g. .
