Abstract:
An inherently pliable polymeric marking film is disclosed which comprises a film component containing an internally plasticized vinyl chloride copolymer resin, a layer of pressure sensitive adhesive and, in preferred embodiments, a release coated protective liner. In certain embodiments, the polymeric marking film is destructible. The marking film has a small degree of shrinkage, shows exceptional conformability to irregular surfaces and has permanence of mechanical properties upon exposure to elevated temperatures.
Abstract:
A method of preparing N-phosphonomethylglycine comprising; (a) reacting N-hydroxymethyl haloacetamide with a chlorinating agent, preferably thionyl chloride to form N-chloromethyl haloacetamide; (b) reacting N-chloromethyl haloacetamide with a phosphite to form N- haloacetylaminomethyl phosphonate; (c) reacting the phosphonate with derivative of haloacetic acid to form N-haloacyl-N-(cyanomethyl or carboalkoxymethyl) phosphonate; and (d) hydrolyzing this later phosphonate to yield N-phosphonomethylglycine.
Abstract:
Gas streams containing low concentrations, e.g., under 20 vol. %, of H 2 S can be treated in a liquid phase Claus reactor under superatmospheric pressure. The use of such higher pressures aids in solubilizing the H 2 S and allows for its removal from such streams even though it is present in very dilute form.
Abstract:
Compounds and compositions containing them, for insecticidal control, particularly for use as soil insecticides, have the formula in which R 1 is methyl or ethyl and R 2 is an α- or β-branched alkyl group having from 3-8 carbon atoms.
Abstract:
