Yield	Reaction Conditions	Operation in experiment
	at 347 - 366℃; under 67506.8 - 72007.2 Torr;Product distribution / selectivity;	EXAMPLESThe synthesis of NEP was carried out continuously under the conditions indicated below in a production plant which corresponded largely to the process concept described above, i.e. the starting materials GBL and MEA were preheated in a recuperative heat exchanger and two steam-heated heat exchangers and fed to the synthesis. In one of the columns following the synthesis, the excess ethylamine and the water introduced into the process were separated off and discharged from the process. In a second column, the removal of the residue and the pure distillation of the product were carried out. Work-up and reuse of the ethylamine separated off in the first column were dispensed with.The reactor was operated in a single pass in the upflow mode. The starting materials monoethylamine (MEA) and GBL were preheated and conveyed by means of pumps to the reactor inlet where the two streams were mixed. The total water content of the starting materials was 14% by weight.The reaction was carried out under the following conditions during the production experiment: Experiment No. 1 Temperature: 347-355 C. Pressure: 90 bar Space velocity:0.6 kg Of GBL/(lreactor· h) Molar ratio of MEA:GBL 1.04 Experiment No. 2 Temperature: 353-366 C. Pressure: 96 bar Space velocity:1.2 kg of GBL/(lreactor· h) Molar ratio of MEA:GBL 1.14 Space velocity through the reactor in kg of GBL per liter of reactor volume and hour.The composition of the product stream obtained in the production plant is shown in the following table.

Ireactor) (experiment 1) or 1.35 kg of NEP/(h ? Ireactor) (experiment 2).
