Abstract: A process for the removal of water from a mixture comprising water and zinc chloride, which comprises adding to said mixture comprising water and zinc chloride an aprotic, polar diluent whose boiling point in the case where an azeotrope is not formed between said diluent and water under the pressure conditions of the distillation mentioned below is higher than the boiling point of water and which is in liquid form at this boiling point of water or which forms an azeotrope or heteroazeotrope with water under the pressure and temperature conditions of the distillation mentioned below, and distilling the mixture comprising water, zinc chloride and the diluent with removal of water or said azeotrope or said heteroazeotrope from this mixture, giving an anhydrous mixture comprising zinc chloride and said diluent.

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 and a head temperature of between 25 ~C and 54 ~C in the absence of a volatile stabiliser. A discharge stream, containing purified anhydrous hydrocyanic acid 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.

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.
