Then ultrasonic wave and solvent were exerted into the crystallizable solution to change its natures,adjust the formation of crystal water and affect the change of crystal configuration.
The article is about how to use phosgene and p-nitrophenylamine to react in acetic ether's liquefier to produce p-nitro-phenyl isocyanate, Its best technological condition have been discussed.
When the solent front move to the other end，take the paper or plate out of the chamber.After the solvent is vapourized，make the chromatogram visiable by some means.
The company main product includes: High boiling point products and so on solvent series, plasticizer series, aromatic hydrocarbon series, Zhong propyl butyl-carbinol, 2- octanone and thiophen.
At the same time, in line with the organic solvent concentration around continues to increase, easily due to static electricity produced by filmogen and burst fire.
The content of free acetic acid in cigarette smoke condensates was determined by GC-MS with isopropyl alcohol as the solvent and nonanol as the internal standard.
The product is a well balanced cleaner and maintainer based on hard waxes and solvents. It cleans while maintains and protects floors and buffable protective film.
Etodolac was synthesized with 7-ethyltryptophol and methyl 3-oxopentanoate as the starting materials.Highly pure etodolac was obtained by purifying the crude product with a mixing solvent.
Tigogenin was separated completely from the crude sapogenins by macroporous resin column chromatography,only simple solvent Ilelute was used in the column of the separate process.
Keto-enol tautomerizing of ethyl acetoacetate was studied by UV.It was conformed that the content of enol ethyl acetoacetate decreased with the increasing polarity of solvents.
