Study on the synthesis of β-naphthyl ethyl ether under microwave radiation;

β-naphthyl ethyl ether is synthesized from β-naphthol and ethyl alcohol by using nanometer complex heteropoly acid as catalyst.

Synthesis of naphthylacetic acid by naphthalene and chloroacetic acid;

This paper desciribes a direct determination of naphthylacetic acid by gas chro-matographrhy with a column solided with GDX-202(80～100mesh).

When rice roots were soaked with naphthylacetic acid(NAA) and uniconazole before transplanting or sprayed on plants before heading, rice root growth, root vigor and function were improved at grain-filling and ripening stages, and root senescence was delayed.

Synthesis of new technics of β-naphthol ethyl ether;

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.
