Method for continuous preparation of nitriles in a pipelined reactor (by machine translation)

The method comprises the following steps that a tin catalyst is coated on the inner wall of the pipeline reactor; and the method comprises the following steps: coating a tin catalyst on the inner wall of the pipeline reactor. The amide solution and the catalytic auxiliary agent are mixed and then sent to a pipeline reactor, and the amide is dehydrated to generate nitrile at the reaction pressure of 0.1 - 2.0 mpa and 100 - 200 °C reaction temperature. The resulting reaction product was separated to give the crude product of the nitrile to which the amide corresponded. In the pipeline reactor, the corresponding nitrile is continuously prepared under the action of the tin catalyst, a dehydrating agent is not needed, byproducts only are water, and three wastes are reduced.

Method for preparing nitrile by reacting acetone cyanohydrin with haloalkane

The invention provides a method for preparing nitrile by reacting acetone cyanohydrin with haloalkane. According to the invention, by using acetone cyanohydrin as a cyaniding reagent, the problems, such as long reaction time, low yield, strict reaction conditions and the like enchanted in an existing preparation method in which highly toxic sodium cyanide or potassium cyanide or expensive trimethylsilyl cyanide is used as a cyanogen source, are solved. The method comprises the following steps: dissolving acetone cyanohydrin in a mixed solvent of a high boiling point dipolar aprotic solvent anda low boiling point aprotic solvent, adding a catalyst lithium hydroxide, stirring at 25-50 DEG C for one hour and then adding a haloalkane for continuous reaction for 2-3 hours; next, adding saturated saline water for washing twice, separating out an organic layer, and boiling off the solvent after drying, thereby obtaining a nitrile compound. The method for preparing a nitrile compound disclosed in the invention is characterized by low reaction toxicity, simple process, easy of operation, low production cost, and a yield of more than 95%.

Process for the preparation of acyl cyanide compounds

Acyl cyanides of the formula STR1 wherein R is alkyl or substituted alkyl with 1 to 8 carbon atoms, or cyano-carbonyl substituted alkyl, i.e., containing another STR2 group, cycloalkyl or substituted cycloalkyl with 3 to 12 carbon atoms or aryl or substituted aryl or represents an optionally substituted 5-membered or 6-membered heterocyclic radical which can additionally also be fused with a benzene ring, Are made by reacting the corresponding acid halide with an alkali metal cyanide or anhydrous hydrocyanic acid in the presence of a heavy metal cyanide and optionally in the presence of a diluent, at a temperature of between 100° C. and 300° C.
