Abstract:
IMPROVEMENTS IN REACTIONS FOR PRODUCING ORGANO ALUMINUM COMPOUNDS ARE DESCRIBED. THE IMPROVEMENTS INVOLVE CONTROL OF THE PROPORTIONS OF REACTANTS FED FOR REACTIONS INVOLVING ALUMINUM, OLEFIN AND HYDROGEN IN THE PRESENCE OF AN ORGANO ALUMINUM COMPOUND. IT IS DISCLOSED THAT SIGNIFICANTLY INCREASED REACTION RATES ARE OBTAINED WHEN OLEFIN AND HYDROGEN ARE FED AT A RATIO SUBSTANTIALLY HIGHER THAN THE 2:1 MOLAR RATIO TAUGHT AS SUITABLE OR EVEN UNIMPORTANT BY MUCH OF THE PRIOR ART.
Abstract:
A process is disclosed for preparing dibromomethane from the reaction of, in the presence of an inert solvent, alkali metal bromide and dihalomethane.
Abstract:
It is disclosed that high purity alkali metal salts of carboxyalkoxy succinic acid are produced from maleic acid and a hydroxy organic acid by reaction of zinc or alkaline earth metal salts of said acids to form a zinc or alkaline earth metal carboxyalkoxy succinate, by reacting the zinc or alkaline earth metal carboxyalkoxy succinate with an alkali metal carbonate in a stoichiometric deficiency of carbonate to selectively react with the alkaline earth metal carboxyalkoxy succinate, leaving the impurities as insoluble alkaline earth metal salts, removing the zinc or alkaline earth metal as insoluble carbonate, and recovering an alkali metal carboxyalkoxy succinate solution which is then evaporated to dryness.
Abstract:
A process for the preparation of alkali metal aluminum tetraalkyls by a redistribution reaction between tetraalkyllead compounds and alkali metal aluminum tetraalkyls. Their use as intermediates for the production of triethyl aluminum compounds.
