entraining nitrogen


Explanation:
Dieser wird abgesaugt, mit Acetonitril (260 mL, auf 0-5 <0>C gekühlt) nachgewaschen und über Nacht bei 45 <0>C im VTS mit Schleppstickstoff getrocknet. So werden insgesamt 424,3 g N-(2-Brom-6-fluorphenyl)-N'-[2-methoxy-5-(trifluormethyl)phenylJHarnstoff als Feststoff erhalten, entsprechend 99,2 % der Theorie. https://patents.google.com/patent/EP1893587A1

This is suction filtered, washed with acetonitrile (260 mL, cooled to 0-5 0 C) washed and dried overnight at 45 0 C in the VDO using entraining nitrogen. Thus, a total of 424.3 g of N- (2-bromo-6-fluorophenyl) -N '- [2-methoxy-5- (trifluoromethyl) phenylJ- urea as a solid, corresponding to 99.2% of theory. https://patents.google.com/patent/EP1893587A1/en

Das erhaltene kristalline Produkt wird durch Zentrifugieren isoliert mit kaltem Acetonitril (zweimal ca. 13 l) gewaschen und bei 45°C im VTS mit Schleppstickstoff getrocknet (ca. 3,5 h). https://patents.google.com/patent/DE102012101680A1/de

The crystalline product obtained is isolated by centrifugation with cold acetonitrile (twice ca. 13 l) and dried at 45 ° C in the VDO using entraining nitrogen dried (approximately 3.5 h). https://patents.google.com/patent/DE102012101680A1/en

This isn't my specialty at all. It could also be "entrained nitrogen." The methanol is passed through suitable indoor piping to the furnace. With a pressurized gas system, a portion of the nitrogen becomes entrained in the methanol and the entrained nitrogen has an adverse effect on the performance of flowmeters in the system. The gas accumulates as bubbles in the flowmeter causing the float of the flowmeter to move erratically and promoting erroneous flow readings. http://www.freepatentsonline.com/5174944.html

agree  herbalchemist: I think "nitrogen (for use as carrier gas for methanol)," but I would like more info.

Explanation:
one of very many examples:

This is common practice for the application you describe though more context would be useful.
