Eight novel N,N′-naphthalene acyl substituted aromatic acylamino thiocarbamides(Ⅱ1~Ⅱ8) were synthesized from aryl acylhydrazine(Ⅰ) and α-naphthalene acyl isothiocyanate, which was obtained by the reaction of potassium thiocyanate with α-naphthalene acyl chloride obtained from 2-naphthylacetic acid and thionyl chloride in anhydrous benzene.

A novel compound——N-naphthalene acylN′-substituted p-chlorobenzamido thiocarbamide was synthesized by reaction of p-chlorobenzamido hydrazine and α-naphthalene acyl mustard oil,which was obtained by potassium thiocyanate combined with α-naphthalene acyl chloride formed from α-naphthylacetic acid and SOCl2 in anhydrous benzene.

Edible Membrane Studies on Deacetyl Konjac Glucomannan;

Deacetyl Modification of Konjac Glucomannan(KGM) by alkali and the effects of different times of alkali treatment on mechanical properties and nanometer-scale micromorphological features of membranes from KGM were explored.

Based on the method of Lemieux, this paper applies a carbohydrate compounds synthesis method to phenol compounds synthesis, and reports for the first time a convenient and efficient procedure developed for conversion of phenol protective group from acetyl to benzyl with BnBr and KOH in refluxing THF in one-pot.

Effect of Deacetylation in Course of Konjac Glucomannan Carboxy Methylation and Structure Characterization of the Products;

Abstract: Some methods of characterization and determination of transiormation ratio irorn acetylamine to amine in the deacetylation of chiun have been reviewed and evaluated.
