Title: Improvements in and relating to the oxidation of aromatic hydrocarbons
Inventor: BERNEIS KURT HELMUT
IPC: C07C409/10
Filed: 1953-10-12
Abstract: Tertiary hydroperoxides are made by oxidizing an aromatic hydrocarbon of the formula Ar.R, where Ar is a phenyl group or a substituted derivative thereof and R is either an alkyl group having a tertiary carbon atom adjacent to the nucleus or a cyclohexyl group, in liquid phase in absence of added water with a gas containing free oxygen, in presence of a peroxide oxidation initiator capable of initiating a free radical oxidation chain, and as stabilizing agents both a carbonate and a weak organic acid salt of an alkali metal, an alkaline earth, or magnesium, the total quantity of stabilizing agents being at least 1.5 per cent of the weight of aromatic hydrocarbon employed, and the weight ratio of carbonate to weak organic acid salt being in the range 1 : 2 to 2 : 1.  The weak organic acid may be any acid weaker than acetic, e.g. stearic, palmitic, lauric, or the mixture of fatty acids obtained by hydrolysis of fats.  The reaction temperature may be 50-100 DEG  C. Inert diluents, e.g. chlorbenzenes or tetrachlorethane, may be employed.  Examples describe the oxygenation of cumene and diisopropylbenzene in presence of the corresponding hydroperoxides, of sodium carbonate and sodium stearate, and of cumene similarly, using calcium carbonate and stearate in place of the sodium salts. The cymenes, sec-butyl-benzenes, and cyclohexyl-benzenes may be similarly treated.

Title: Process for preparing alkyl aluminium sesquihalides
IPC: C07F5/06
Filed: 1960-08-12
Abstract: Alkyl aluminium sesquihalides of formula RxAl-Haly wherein R is C1-4 alkyl, Hal is chlorine, bromine or iodine, x and y are each greater than zero and (x+y)=3 are made by (i) adding an alkyl aluminium sesquihalide and an alkyl halide to metallic aluminium while confining the reaction zone of the alkyl halide and aluminium to a film, (ii) dissipating the heat of reaction by vaporization of unreacted alkyl halide which is thereby removed from the reaction zone, and (iii) removing the liquid film from the aluminium to obtain the sesquihalide. Preferably R in the added sesquihalide is the same as the R in the alkyl halide.  The alkyl halide in excess of that required to react with the aluminium is dissolved in the alkylaluminium sesquihalide and sprayed on to the aluminium in the form of chips, which are kept in a state of agitation at a relatively fast rate. The reactor may be heated if desired to above the boiling point of the alkyl halide in order to initiate the reaction.  The process may be carried out batchwise or preferably, continuously.
