Abstract: A process for thermally-degrading the thermally-degradable organic matter contained in spent sulfuric acid by condensing steam in the spent acid for a time sufficient to degrade the thermally-degradable organic matter, the steam being at a pressure exceeding the vapor pressure of said spent acid. Treated sulfuric acid is useful in the production of wet process phosphoric acid by a novel process. Spent sulfuric acid containing non-degradable organic matter can be used in a mixture with the treated sulfuric acid.
Abstract: Compounds having the formula ##SPC1##In which R is hydrogen, lower alkyl, lower alkenyl, lower alkoxy, halogen, nitro; or lower alkylthio; X is chlorine or bromine; A and B are each hydrogen, together form an epoxide link or together form a bond; the use of these compounds in controlling insects; and a method of preparing these compounds.
Abstract: Compounds having the formula ##EQU1## in which R is alkyl having from 1 to 6 carbon atoms. The compounds are useful in inhibiting the growth of bacteria and fungi.
Abstract: Compounds having the formula ##EQU1## in which R is (1) alkyl or (2) allyl; R.sup.1 is alkyl; R.sup.2 is alkyl; and R.sup.3 is (1) hydrogen, (2) lower alkylthio, (3) cyano, (4) phenylthio, (5) substituted phenylthio wherein the substituent is halogen, (6) ethynyl, or (7) CCl.sub.2 =CH--, their use as insecticides and acaricides, a process for preparing the compounds, intermediates having the formula ##EQU2## where R is alkyl or allyl, R.sup.1 is alkyl and R.sup. 2 is alkyl and useful in preparing the above compounds and a process for preparing the intermediates.
Abstract: Compounds having the formula ##SPC1##In which R and R.sup.1 are independently methyl or ethyl; n is the integer zero or one; R.sup.2 is hydrogen, lower alkyl, lower alkenyl, lower alkoxy, halogen, nitro, lower alkylthio, or certain hetrocyclic radicals; the use of these compounds in controlling insects; and a method of preparing certain intermediates which are useful in preparing certain of the compounds.

Abstract: Compounds having the formula ##EQU1## in which X is chlorine or bromine, R is hydrogen or alkyl having from 1 to 6 carbon atoms; R.sup.1 is alkyl having 1 to 4 carbon atoms or haloalkyl having from 1 to 4 carbon atoms; phenyl or nuclear substituted derivatives thereof in which the substituents are halogen, nitro or lower alkyl, R.sup.2 is alkyl having from 1 to 6 carbon atoms or haloalkyl having from 1 to 6 carbon atoms. The compounds are useful in controlling weeds and for inhibiting the growth of bacteria and fungi.
Abstract: Compounds of the formula ##EQU1## in which R is alkoxy having 1 to 5 carbon atoms; R.sup.1 is alkyl having 1 to 5 carbon atoms or alkoxy having 1 to 5 carbon atoms; X is hydrogen, chlorine, bromine, methyl, methoxy or ethoxy and Y is hydrogen, chlorine, bromine, methyl, methoxy or ethoxy as insecticides, acaricides or herbicides.
Abstract: N-t-butyl-.alpha.-(3,5-substituted phenoxy) alkyl amides compounds having the formula ##SPC1##In which R.sup.1 and R.sup.2 are independently halogen or alkyl; R.sup.3 is alkyl; and their use as herbicides.
Abstract: A process is disclosed for the recovery of dialkylaluminum halides from a mixture containing dialkylaluminum halides and soluble zinc containing compounds by heating the mixture to pyrolyze the zinc compounds down to acceptable levels and subsequently distilling the alkylaluminum halide from the heated mixture.
