In the production of caprolactam by reaction of 1,1'-peroxydicyclohexylamine with alkali metal alkoxides, the reaction is carried out in a reaction medium which is a mixture of methanol and dimethylsulphoxide.

Irradiation of material in packages is carried out continuously by a unique conveyor arrangement which transports closely spaced carriers containing the packages in vertical runs past a radiation source. The radiation conveyor utilizes extension arms to increase the radius of outside turns and allow the carriers to be spaced closer to the source and to each other. A transfer conveyor is provided to obviate the need for inside turns so that individual carriers and adjacent vertical runs may be cl...

Production of anthraquinone by catalytic oxidation of indans with oxygen. Anthraquinone obtainable by the process is a starting material for the production of dyes and pesticides.

A process for the production of a nitroalkane or dinitroalkane by reacting an olefin or diolefin with nitric acid in the presence of a lower aliphatic monocarboxylic acid anhydride, thereby producing a nitro-ester or dinitro-ester, and reducing the nitro-ester or dinitro-ester with an alkali borohydride to produce the nitroalkane or dinitroalkane.

Production of polyacyloxalamidrazones, especially a very high molecular weight polyterephthaloyloxalamidrazone having recurring units of the formula by an interfacial polycondensation of oxalic acid bisamidrazone with an acyl dihalide monomer such as terephthalic acid dichloride at temperatures of 0.degree.C. to 60.degree.C. in a two-phase solvent system consisting essentially of water and a water-immiscible, inert organic solvent, in the presence of an acid acceptor and in the presence of a sub...

Process for the preferential formation of acetonitrile in vapor phase ammoxidation of acrolein or products producing acrolein by carrying out the reaction at a relatively low temperature and at a high ammonia to acrolein ratio.

A two-stage process for the production of thiourea from hydrogen sulfide and calcium cyanamide in which the hydrogen sulfide is introduced into an aqueous suspension of the calcium cyanamide in a first stage at temperatures below about 80.degree.C. and advantageously no higher than about 40.degree.- 60.degree.C. under a reduced pressure of less than about 300 mm. Hg and the resulting mixture is then further reacted in a second stage at about 60.degree.C. to 100.degree.C. under approximately norm...

Ethylene is converted to linear monoolefins of a selected range of carbon atoms by (1) oligomerizing ethylene to linear .alpha.-olefins (2) separating the linear .alpha.-olefins into a lower .alpha.-olefin fraction, and intermediate .alpha.-olefin fraction of a selected range of carbon atoms and a higher .alpha.-olefin fraction (3) recovering the intermediate .alpha.-olefin fraction as product (4) isomerizing and disproportionating at least a portion of the lower and higher .alpha.-olefin fracti...

1,1,3,3-Tetrafluoropropan-2-ol and 1,1,1,3,3-pentafluoropropan-2-ol are prepared by the vapor phase catalytic halogen hydrogenolysis and carbonyl reduction of perhaloacetones with hydrogen employing a supported palladium on carbon catalyst.

A process for producing gasoline from a hexane-rich hydrocarbon feed which comprises disproportionating the hexane-rich feed to obtain at least C.sub.5 hydrocarbons and C.sub.7 + hydrocarbons, and catalytically reforming the C.sub.7 + hydrocarbons to obtain reformate. Preferably, the normal pentane hydrocarbons obtained from disproportionating the hexane are fed to a C.sub.5 isomerization process to obtain isopentane. Preferably, a common fractionation zone is used for the disproportionation, ca...
