(1) One is triphenyl phosphite ozonide, the other is 3-(4-nitrophenylsulfonyl)-2-phenyl-2-thioxo-1,3,2-oxazaphospholidine.

(2) A method for preparing dimethyl phosphite was developed from methanol and phosphorous trichloride.

(3) Dibenzyl phosphite was synthesized by benzyl alcohol and trichlorophosphorous in the presence of pyridine.

(4) A bis- phosphite antioxidant, 2,4-di-test-butylphenyl phosphite , antioxidant 626, was synthesized by a new technology.

(5) The iron phosphite eutectic and ledeburite in wearre-sistant cast iron are contradistinguished with metallography and microhardness and scanning electron microscope.

(6) As shown by results, phosphite in cathodal cell was really converted into hypophosphite to a certain extent but its conversion rate was low due to the confinement of decomposition voltage.

(7) Four compounds of phosphite ester and phosphoramide containing azido groups were synthesized. The molecular structure of the products has been confirmed by IR, 1HNMR, FAB MS and elemental analysis.

(8) Triisopropyl phosphite was synthesized and isopropanol using pyridine as an organic base.

(9) Oxidronate was prepared from triisopropyl phosphite by diphosphonation, chlorination, pyrolysis and reduction with 32 % overall yield.

(10) Diisopropyl phosphite was directly synthesized from phosphorus trichloride and isopropanol by using the solvent method.

(11) Its anticorrosive property is much better than zinc phosphite, zinc phosphate and red lead.

(12) Hyperbranched aromatic polyamides were prepared by direct polycondensations of the two monomers in the presence of triphenyl phosphite and pyridine as condensation agents in NMP.

(13) The synthesizing of dimethyl methyl phosphonic acid ester with trimethyl phosphite was catalyzed by methyl alkylbenzenesulfonate.

(14) METHODS:Clodronate was synthesized by steps of condensation, chloration, pyrolysis and salifying from dibromomethane and triisopropyl phosphite.

(15) In this paper, three alkyl substituted dimethyl phosphonates have been synthesized by trimethyl phosphite with 1-Bromopentane, 1-Bromohexane and 1,2-Dibromoethane. Sentencedict.com

(16) Moreover, the polybenzimidazole resin(PBI)from TADE monomer and diphenyl isophthalate(DPIP) monomer was further polymerized in the present of triphenyl phosphite(TPP) catalyst.

(17) According to the structure and oxidation mechanism of rosin, the light-colored reaction of polymeric rosin with phenols, phosphite ester, thioester and etc.

(18) A white or yellowish hygroscopic crystalline solid, H3PO 3, used as a reducing agent and to produce phosphite salts.
