Abstract: A process for the preparation and recovery of m,m'-dinitrobenzophenone and which comprises reacting benzophenone with nitric acid in oleum; adjusting the reaction product to a water content from 12 to 30 weight percent; and extracting the m,m'-dinitrobenzophenone with a chlorinated hydrocarbon solvent.

Abstract: Acrylonitrile is produced by passing a gaseous mixture comprising propylene, molecular oxygen and ammonia upwardly through a fluidized bed comprising particles of a highly-active acrylonitrile catalyst in physical admixture with particles of a composite consisting essentially of antimony oxide and silica. The use of the antimony oxide-silica composite moderates the effect of the highly-active acrylonitrile catalyst reducing its activity sufficiently to enable the use of longer residence times, but without reducing the acrylonitrile selectivity of the catalyst.

Abstract: A spotting fluid comprising an oily material containing a solid spotting agent, said solid spotting agent comprising at least 20 weight percent of said oily material and at least 32 pounds per barrel of said solid spotting agent, said solid spotting agent comprising substantially spherical particles having a specific gravity of at least 2.0, an average particle diameter below 212 microns, and a compressive strength of at least 5000 psi is used to free a differentially stuck drill string.

Abstract: A catalyst support suitable for use in a cracking process or hydrotreating process. The catalyst support comprises a magnesia-alumina-aluminum phosphate matrix which has outstanding thermal stability.

Abstract: An alpha olefin is polymerized to obtain highly crystalline polymers by subjecting the alpha olefin to polymerization conditions using as a catalyst therefor the reaction product of (A) an aluminum hydrocarbyl treated with an electron donor compound and (B) a support containing chlorine, bromine and magnesium, wherein the molar ratio of bromine to chlorine ranges between about 1:99 to about 50:50, preferably between about 2.5:97.5 to about 20:80, and most preferably between about 2.5:97.5 to about 15:85, obtained by reacting an organo magnesium compound with a mixture of chlorinated and brominated aluminum compounds, the support having been additionally treated with an electron donor compound and with titanium tetrachloride. The molar ratio of magnesium to combined chlorine and bromine in the support is not critical but generally ranges between about 1:1.6 and about 1:2.0, preferably between about 1:1.8 and about 1:2.0.

Abstract: Corn is protected from S-alkyl thiocarbamate herbicides, while obtaining good control of unwanted plant species by applying to the soil in the vicinity of corn seed an effective but non-phytotoxic amount of an N,N-diisopropyl, N-benzyl-N-methyl, N-benzyl-N-ethyl, N-(p-methoxybenzyl), N-methyl-N-phenethyl or N,N-diethyl amide of dichloroacetic, dibromoacetic or tribromoacetic acids.

Abstract: This invention relates to the inhibition of microbial growth in liquid distillate hydrocarbon fuels and more particularly to the use of halonitro alcohols as microbicides which effectively inhibit microbial growth in liquid distillate hydrocarbon fuels when incorporated therein at low concentrations.

Abstract: A liquid dielectric composition obtained as a result of a process which comprises reacting benzene with ethylene in the presence of an alkylation catalyst to obtain an alkylation product containing largely unreacted benzene, ethylbenzene, polyethylbenzenes, 1,1-diphenylethane and heavier products, separating benzene, ethylbenzene, polyethylbenzenes and 1,1-diphenylethane from said alkylation product and thereafter recovering from said heavier products a fraction having a boiling point in the temperature range of about 275.degree. to about 420.degree. C., preferably about 280.degree. to about 400.degree. C., as said liquid dielectric composition.

Abstract: An improved method for presulfiding a hydrodesulfurization catalyst which comprises continuously contacting the catalyst with a sulfiding treating agent at a relatively low temperature and pressure and only until the total amount of sulfur in the treating agent contacting the catalyst is no more than 55 percent of the amount of sulfur required to sulfide the supported metals on the catalyst to their completely sulfided forms.

Abstract: A liquid dielectric composition obtained as a result of a process which comprises reacting benzene with ethylene in the presence of an alkylation catalyst to obtain an alkylation product containing largely unreacted benzene, ethylbenzene, polyethylbenzenes and heavier products, separating benzene, ethylbenzene and polyethylbenzenes from said alkylation product and thereafter recovering from said heavier products the entire fraction whose boiling point is in the temperature range of about 255.degree. to about 420.degree. C., preferably about 260.degree. to about 400.degree. C., most preferably about 268.degree. to about 400.degree. C., as said liquid dielectric composition.

Abstract: Insects and mites are combated by applying to the locus of insects in at least one stage of the insects' life cycle an effective amount of a compound having the structural formula ##STR1## in which X and X' may be oxygen or sulfur, R may be alkyl, cycloalkyl, aryl, alkenyl, alkynyl, optionally substituted with halogen, hydroxy, alkoxy, nitro, mercapto or alkylthio substituents, R' may be hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, aryl etc., and if R' is not hydrogen one of R" and R"' may be hydrogen while one or both may be alkyl, optionally substituted with halogen, hydroxy, alkoxy, mercapto or alkylthio substituents or R" and R"' together may be part of a heterocyclic ring containing 2 to 6 carbon atoms, with the provision that the total of R, R', R" and R"', must contain from 4 to 9 carbon atoms and if R is straight chain alkyl having less than 6 carbon atoms, none of R', R" and R"' may be hydrogen. The novel insecticides are particularly useful in combating aphids.
