Nonnatural amino acid 3-(4-thiazolyl)-D,L-alanine hydrochloride and its four intermediates were synthesized, their structures were detenmined by IR,NMR,elementary analysis and melting point.
Different solvent extractions of Spora Lygodii were obtained using methanol,chloroform and petroleum ether as medium.Experiments were carried out on them by FT-IR spectra.
Abstract: Objective To evaluate the clinical efficacy of dimethyldiguanide and Gliclazide capsule in treatment of type 2 diabetic insulin resistance (IR) and fat metabolism disorder.
This paper uses orthogonal experiment to research on the synthesis technique of pseudo-ally lionone from citral and allylacetone. The product structure had analysed by IR.
To provide proof of grafting, modified hydrolysate was identified by indanthrone, the IR and amino acid composition analysis of hydrolysate and modified hydrolysate were studied.
Through IR analysis, the main component in group II was identified as dialkyl-benzene, while in Group III was monoalkyl-benzene as well as dialkyl-tetralin and indane (DTI).
Using lead benzoxy as curing agent,cured epoxy resin was analyzed by means of IR spectrum and DSC curves.Lead benzoxy was considered to be catalytic curing agent.
S-Methyl-isothiourea sulfate was oxidized by hydrogen peroxide to give methylsulfonyl chloride in 70% yield in aqueous hydrochloric acid solution.The product was characterized by 1HNNR and IR.
Abstract: Using lead benzoxy as curing agent,cured epoxy resin was analyzed by means of IR spectrum and DSC curves.Lead benzoxy was considered to be catalytic curing agent.
However, absorption peak of Sexadentate Titanium was not detected at the high temperature. it might not be detected by IR Spectra because of too little Titanium phase.
Moreover, the results of IR spectrum and apolar component of surface free energy showed that the alkyl chains of OTS tilted on the surface of PTW after the modification.
The IR spectra of hydrogel, alcogel and aerogel of BaFe12O19 were studied, and the ones of the powders calcined at different temperatures for different time were also studied.
