Abstract: Aluminum salts of N-nitroso-N-alkylhydroxylamines are produced by the reaction of an aluminum salt with an alkali metal salt, alkaline earth metal salt and/or ammonium salt of an N-nitroso-N-alkylhydroxyl-amine and/or the aftertreatment of an appropriate aluminum salt in the presence of water and an organic solvent. The products have fungicidal properties and are starting materials for the production of fungicides for wood preservatives, colored surface coatings, synthetic resins and dye formulations.

Abstract: Pinacol is prepd. by the electrolhydro-dimerisation of acetone in partitioned cell using as electrolyte a catholyte contg. 10-90 wt % acetone, 1-60 wt % water and 1-50 wt % to a quat. ammonium salt. The pref. amts. are 40-80 wt %, 5-30 wt % and 5-20 wt % respectively. The cell is pref. divided by porous membranes of cation exchangers e.g. sulphonated reticulated polystyrene. The anode may be Pb coated with PbO2, graphite or Ti esp. in combination with 1-10 wt % H2SO4 as anolyte. The cathode may be Cu, Ag, Cd, Zn, Sn, Pb, Tl or Hg but is pref. graphite or a plastic matl. filled with graphite. The quat. cpd. is e.g. of formula (I): (where R1-4 are each 1-6C alkyl, aryl or aralkyl and X- is an anion such as sulphate, alkylsulphate, phosphate, carbonate, tosylate, BF4-, SiF6- halide or perchlorate). Process may be continuous or discontinuous, give improved yields per unit of current over known methods and avoids the necessity of neutralising acids in soln.

Abstract: Method for purifying lactams by passing their vapours at temps. higher than their condensation point over or through activated carbon. Residence time is pref. 1-5 (esp. 2-3) sec. For epsilon-caprolactam, temp. used is 180-300 degrees C. Inert gas is opt. present. The carbon can be regenerated by solvent-extraction or superheated steam.
