Process for the continuous preparation of N-ethyl-2-pyrrolidone (NEP) by reacting gamma-butyrolactone (GBL) with monoethylamine (MEA) in the liquid phase, wherein GBL and MEA are used in a molar ratio in the range from 1:1.08 to 1:2 an the reaction is carried out at a temperature in the range from 320 to 420&#xb0; C. and an absolute pressure in the range from 70 to 120 bar.

Process for continuously preparing N-ethyl-2-pyrrolidone (NEP)

The present invention provides a process for preparing propargyl alcohol by converting an aqueous formaldehyde solution comprising acetylene over a catalyst comprising copper acetylide at an operating pressure of from 1 to 15 bar and from 70 to 120&#xb0; C. without forming a continuous gas phase, in which the aqueous formaldehyde solution comprises an organic solvent for acetylene and the catalyst is arranged in a fluidized bed.

Method for the production of propargyl alcohol

A metal oxide-containing catalyst which also contains, besides oxides of titanium and/or zirconium, oxides of vanadium and/or niobium and oxides of molybdenum, tungsten, and/or chromium, sulfates of alkaline earth metals, and which is used in a process for the degenerative oxidation of organic compounds present in exhaust gases from combustion plants.
