niger (IFO 3108), and the resultant acetate compound is solvolyzed with methyl or ethyl alcohol in the presence of a base, e.g. anhydrous K2CO3, in a catalytic amount, etc., at 0-35 deg.C, to give a compound expressed by formula I in high optical purity and relatively high yield...
aBecause the allyl alcohol polyethylene glycol covers the active unsaturated duplet chemical bond, the synthesis of polycarboxylate superplasticizer may realize with a comparatively simpler craft 由于烯丙醇聚乙二醇报道活跃不饱和的duplet化学键, polycarboxylate superplasticizer综合也许体会与一种比较更加简单的...
In industrial production, Benzyl Alcohol is widely used as a cleaning agent and diluent due to its good solubility and low toxicity. It can effectively remove various stains and impurities, while being relatively safe for the environment and the human body. Because of its unique chemical ...
(monolithic type). Drugs can also be carried in a polymer-drug conjugate manner, and targeting factors can be introduced to transport drugs to specific disease sites through the physical and chemical properties of the polymer, such as active or passive targeting [82]. When polymer-based ...
We describe the structure of the new [Cr(2-pic)2(OH2)2]NO3 complex compound where 2-pic denotes the 2-pyridinecarboxylate anion. Moreover, the catalytic activity of the 2-pyridinecarboxylate complex of chromium(III) has been studied in the case of the 2-chloroallyl alcohol oligomerization....
Glucose and amino acids (glycine, valine, and cysteine), castor oil from AL-Nasr Pharmaceutical Chemical Co., Egypt. Sodium hydroxide, acetone, ethyl alcohol, methanol, petroleum ether, SOCl2, and chloroform were analytical grade chemicals. Silica gel, 200–300 mesh, was used for column ...
Interestingly, the addition of DES led to intensifying the COH groups in regard to COC bonds. This is related to the chemical structure of HBDs, which end with COH groups. The addition of this substrate increases the share of these groups in the structure of the chitosan-based films. 3.2....
A target and non-target strategy for identification or characterization of the chemical compound in Chinese herb preparation Shuang-Huang-Lian oral liquid by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry Biomedical Chromatography, 32 (3) (2018), Article e4110 View ...
1). The compounds were identified as follows by comparison of their spectroscopic and physical data with those previously reported in the literature: 3-methoxy-4-hydroxybenzyl alcohol (1)10, β-hydroxypropiovanillone (2)11, 1-(4-hydroxy-3-methoxyphenyl)-glycerol (3)12, 3,5-dimethoxy-4-...
