Abstract: Dialkylaluminum hydrides are produced by subjecting a mixed aluminum alkyl having the formulaR.sub.2 AlR'to pyrolysis. R is methyl, ethyl, n-alkyl or an alkyl group which has no hydrogen atoms on the carbon atom .beta. to the aluminum. R' is an .alpha.- or .beta. branched alkyl group having the formula ##STR1## in which one R" is hydrogen and the other is alkyl and R'" is alkyl. The mixed aluminum alkyl R.sub.2 AlR' can be obtained either by reaction of two aluminum alkyls:2R.sub.3 Al + R'.sub.3 Al .fwdarw. 3R.sub.2 AlR'or by reaction of a trialkylaluminum with a dialkylaluminum hydride:2R.sub.3 Al + R'.sub.2 AlH .fwdarw. 2R.sub.2 AlR' + R.sub.2 AlH,in which case one third of the desired hydride is synthesized.

Abstract: A mixture of cis and trans isomers of S-isopropyl-1-(5-ethyl-2-methylpiperidinecarbothioate) has been found to have improved herbicidal properties in contrast to the trans isomer alone. Preferably the mixture contains at least about 20%, most preferably between about 60 and about 65%, of the cis isomer.The S-isopropyl-1-(5-ethyl-2-methylpiperidinecarbothioate) having a desired amount of cis isomer can be produced by a two-step process comprising hydrogenation of 2-methyl-5-ethyl pyridine using a catalyst comprising rhodium supported on activated carbon to produce 2-methyl-5-ethyl piperidine and reacting the piperidine with isopropyl chlorothiolformate.

Abstract: A process for production of liquid sulfur trioxide in which sulfur is combusted with oxygen in one stage at a furnace outlet temperature of between about 1000.degree. F and about 2700.degree.
