Catalyst for hydrocracking and method for catalytic hydrodewaxing of gas

The invention relates to improved manufacture of methylene bis-(dibutyl-dithiocarbamate) with ASTM coulour less than 2, by reacting aqueous solutions of dibutyl amine and sodium hydroxide with carbon disulfide, treating the obtained reaction product with methylene dichloride, followed by vacuum stripping, phase separation and filtration of the precipitated sodium chloride. According to the invention, during reaction with carbon disulfide the temperature of the mixture is kept at or below 15.degree. C. and the vacuum stripping is performed in two steps, first between 45.degree. C. and 100.degree. C. and at a pressure of 5-50 kPa, then phase separation is carried out at a temperature between 35.degree. C. and 50.degree. C., followed by stripping the separated organic phase in vacuum also at a temperature between 45.degree. C. and 100.degree. C. and at a pressure of 5-50 kPa.

The invention relates to a process for the production of alcohol-free wine, i.e. wine containing less than 1% by volume of alcohol, and of wines containing reduced concentrations i.e. 1 to 7% by volume of alcohol with the simultaneous production of brandy by using continuous vacuum film distillation with continuous introduction of carbon dioxide and/or an inert gas, producing thereby a dynamic atmosphere of carbon dioxide and/or an inert gas, at the temperature of at most 100.degree. C., preferably 40.degree.-100.degree. C. and in a vacuum of 6.45-25.80 kPa.
