Synthesis and Plant Growth Regulation Activity of α-(4-Chloro-1-naphthyloxy acetoxy)alkyl phosphonates;

Effects of Methylphosphonate Monosodium on Pyruvate Dehydrogenase;

Synthesis and plant growth regulation acivity of α-(1-naphthloxy acetoxy)alkyl phosphonate;

Heteropoly acids(HPAs) were found to be efficient catalysts for one-pot three-component synthesis of α-amino phosphonates in good yields.

Ten new title compounds Ⅰ a￣Ⅰ j were synthesized by condensation of α-chloroacetosyl alkyl phosphonates and sodium 2-mercaptobenzothiazole.

Three new O, O-diethyl-α-[(6-methyl-7-nitrobenzocizal)-2-oxo]phosphonates have been synthesized.

The mechanism and the developments of non-halogen organic flame retardants were discussed in organic phosphorus-based-non-halogen phosphate flame retardants、organic silicon-based flame retardants、non-halogen intumescent flame retardants and nitrogen-based flame retardants.

This paper introduces synthesis for a kind of polyester-phosphate-amine,and imitaled experiments and engine bench contrastive experiments are also discussed.

The programs based on the impr-oved trial-and-error method have been written in FORTRAN77 and tested in Co-ncrete examples, The X-ray diffraction values of powder specimens of unknowncrystal system of diethyl-(2′-hydroxy phenyl) phosphate have been indexed succe-ssfully by the programs, The lattice parameters obt.
