  ethanol molecules
The thermal decomposition of ethanol molecules is observed at a temperature above 623.15 K.
      
The layer consists of ethanol molecules and electroneutral associates of sulfate ions with Cu2+ cations containing crown-ester molecules in the coordination sphere.
      
The best inhibition by crown ether was found to occur in a range of the water structure stabilization by ethanol molecules (where the desalting effect of the mixed solvent ensures the maximum adsorption of additive molecules).
      
Adsorption of NO2 molecules was shown to reduce the density of the heterointerface states, while adsorption of ethanol molecules resulted in its increase.
      
The electrostatic force and energy of the interaction of ethanol molecules with each other and the surface of pores were calculated; the results were compared with the O-H···O H-bond energy.

Characteristics of infrared multiphoton dissociation of ethanol molecules were investigated experimentally. The dependence on dissociation rate on laser frequency, laser energy, pulse number, temperature and initial pressure are given. The maximum value of dissociation rate of ethanol molecules was found to shift by 8 cm-1 towards longer wavelengths relative to the peaks of its linear absorption spectrum.

It is reported the esterification reaction of acetic acid with alcohol on HZSM -5 zeolite. With a series of HNaZSM-5 zeolite catalysts, the effect of the degree of cation exchange on the activities and the selectivities of the catalysts were discussed. The effect of calcination temperature of HZSM-5 zeolite on the activity and the selectivity was investigated. The surface acidity of HZSM-5 zeolite was determined by JR-spectroscopic method. It Was found that the esterification reaction can take place both at the Bronsted acid sites and the Lewis acid sites, while ether was produced mainly at strong Bronsted acid sites. Since the activity of the catalyst was not reduced remarkably by 4-mcthylquinoline, the esterification must mainly occured on the internal surface of zeolite.

The general anesthetics play the action by disordering the construction and fusion of the membrane. The paper studies the effect of four general anesthetics (chloroform, ether, alcohol, octanol) on 3 mmol/L calcium-induced fusion of lipid vesicles composed of PS: DMPC: chloroform = 5:3:2 with suitable fluorescein-labeled phosphatide, the fusion of lipid vesicles was monitored by using fluorescence resonance energy transfer assays. The initial experiment showed, chloroform, ether and octanol can slightly inhibit the membrane fusion within clinical concentration. In contrast to above three anesthetics, alcohol can induce the membrane fusion near clinical concentration. The effect of the induced fusion becomes very apparent, as the concentration increases. This occurs possibly due to the fact that the alcohol molecules have strong polarity, so they may bind to the polar head of phosphatide through hydrogen bond, partly substitute the structure water molecule and deduce the rejection of hydration, so make it easier to get membrane fusion.

全麻剂通过干扰膜的结构与功能而起作用,研究了四种全麻剂(氯仿、乙醚、乙醇及辛醇)对3mmolCa2+诱导融合影响用PS:DMPC:Cholesterol=5:3:2的人工膜脂质体进行实验,脂质体融合用荧光共振能量转移监测,初步实验表明:在临床浓度范围内,氯仿,乙酸及辛醇能轻微地抑制膜融合,而乙醇在临床浓度附近能促进膜融合,并且随着乙醇浓度的提高其促融合效应变得十分明显,这可能是乙醇分子的极性及通过氢键与磷脂头缔结,并取代部份结构水,减弱水化排斥力而促使膜融合。
