Abstract: Disclosed is a method for producing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphite diamides, aminophosphines, diaminophosphines, phosphite amide halogenides, and aminophosphine halogenides by separating an acid in the presence of an auxiliary base. Said auxiliary base b) forms a salt with an acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation of the liquid salt, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible phases in a suitable solvent.

Abstract: The invention is a process for preparing tetraalkyl-substituted biphenol which comprises reacting a 2,4- or 2,6-dialkyl substituted phenol in which the alkyl groups contain 1 to 6 carbon atoms with a peroxidase enzyme in the presence of a peroxide in an aqueous medium to yield a tetraalkyl-substituted biphenol by oxidative coupling of the 2,4- or 2,6-dialkyl substituted phenol, or yielding a tetra-alkyl substituted quinone, and reducing the quinone to obtain a tetraalkyl-substituted biphenol. The invention further includes a process for preparing a tetraaryl-substituted biphenol in which the aryl groups contain 6 to 10 carbon atoms which comprises racting a 2,4 or 2,6 diarylphenol with a peroxidase enzyme to yield a tetraaryl-substituted biphenol. A process for reducing a tetraalkyl-substituted quinone to corresponding tetraalkyl-substituted biphenol which comprises reducing the quinone with a phenol in an aqueous medium at a temperature of about 60° to 120° C. is also included.

Abstract: The invention relates to a method for dehydrating hydrocyanic acid by distillation. Said method is characterised in that a crude hydrocyanic acid containing between 50 and 99.9 wt. % HCN, between 0.1 and 40 wt. % water, between 0 and 15 wt. % carbon oxides and optionally between 0.01 and 1 wt. % non-volatile stabiliser is distilled in a distillation column at a pressure of between 1 bar and 2.5 bar, a sump temperature of between 100 ~C and 130 ~C a nd a head temperature of between 25 ~C and 54 ~C in the absence of a volatile stabiliser. A discharge stream, containing purified anhydrous hydrocyanic ac id and carbon oxides is thus obtained from the head and a discharge stream containing water and optionally the non-volatile stabiliser is obtained from the sump.
