The inclusion complex of benzoic acid with Pcyclodextrin (β-CD) was prepared by the copreci-pitation method. The complex was characterized by FTIR. The optimum inclusion process was deter-mined by orthogonal experiment. It was showed that the molar ratio of β-CD to benzoic acid was...
Preparation of acid formatsAbstractA process is described for preparing acid formates in whichmethyl formate is reacted with water and a basic compound havinga pK[err] of the conjugate acid of the corresponding dissociationstate of [err] 3 measured at 25[err]C in aqueous solution, the methanol...
After 15 min, excess solution was blotted away using a strip of filter paper. The samples were allowed to dry in the atmosphere and at room temperature for 1 day before observation. Phosphotungstic acid (PTA) was used to stain the PEG phase in the copolymer [23]. 2.5. Protein adsorption ...
TFLF was extracted according to the procedure of traditional boiling optimized by orthogonal experiment, and macroporous resin chromatography. The optimal conditions of solid–liquid ratio, extraction temperature, and decocting time were investigated through single factor tests. According to the results of ...
(HCF) composite, which uses a much cheaper benzoic acid (BA; the cost of the analytical-grade product is 16.4 ¥/250 g) as the ligand to replace part of the traditional ligand trimesic acid (H3BTC to synthesize HKUST-1; the cost of the analytical-grade product is 566 ¥/500 g);...
The surface properties of these gels were qualified by the equilibrium adsorption of benzoic acid. The potential for the adsorbent of the gel was estimated... Y Seida,Y Nakano - 《Kagaku Kogaku Ronbunshu》 被引量: 11发表: 1994年 The role of molecular adsorbent recirculating system dialysis fo...
4-(2,5-Dioxo-hexahydro-pyrrolo[1,2-a]imidazol-1-yl)-benzoic acid; 4-(2,5-Dioxo-hexahydro-pyrrolo[1,2-a]imidazol-1-yl)-benzoic acid ethyl ester; 1-(4-Methanesulfonyl-phenyl)-tetrahydro-pyrrolo[1,2-a]imidazole-2,5-dione; 1-(4-Fluoro-phenyl)-tetrahydro-pyrrolo[1,2-a]imidazole-,5...
a 5-hydroxypyrazole is reacted with a 3-(4,5-dihydroisoxazol-3-yl)benzoic acid derivative. The 3-(4,5-dihydroisoxazol-3-yl)benzoic acid derivative required for this process can only be obtained with difficulty, via a large number of steps. Accordingly, the process is relatively expensive ...
4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-anthracenyl) benzoic acid marked with tritium is used as a radioactive marker in the titration of nuclear receptors and CRABP, in the measurement of the aff
As used herein, the term "peptide" is intended to refer generally to both peptides or proteins, and is not intended to imply any size restriction on the amino acid polymer. However, due to the nature of the invention and in that one of its most important applications being site-directed ...
