Study on the conditions of preparing organic montmorillonite under the synergic effect of tetraethyl ammonium bromide and octadecyltrimethyl ammonium chloride;

X-ray powder diffraction(XRD) is used to study and characterize properties of organic montmorillonite.

Property analysis of organic modified montmorillonite by single molecule alkyl quaternary ammonium salts;

In the solution of dimethylglyoxime,sodium nitride and hydroxylamine hydrochloride,the determination of exchangeable content in cobalt modified montmorillonite by single sweep oscillopolarography has been presented.

Four kinds of modified montmorillonites were prepared and characterized by means of X\|ray powder diffraction and elemental analysis.

Organic montmorillonites with different structure were dispersed in organic liquids of dimethylbenzene,ethanol mixture and 0# diesel oil respectively,the gel performance of each organic montmorillonite was measured.

In the former technics, seven distinct kinds of quarternary alkyl ammonium salts are utilized and effects of their dosage, the modification time, temperature on the properties and structures of organic montmorillonite have been te.

Molecular dynamics simulation technique was used to investigate the molecular environment and the alkyl chains arrangement in the interlayer of cation surfactant modified montmorillonite,and the influence caused by water content in organic montmorillonite with different surfactant loading was studied.

The author designes 18 experiments to synthesize the organophilic montmorillonites using orthogonal method and then characterizes them.

The status quato of synthesizing craft ?ways of structure and characteristics signified and application of organo-montmorillonite were introdrced,the focus subjects in the field were explored.

The alkylammonium cations adsorption character in organomontmorillonite(OM) interlayers and gelling properties of OM are important research aspects in the preparation and application of OM.

Using differential thermal analyse(DTA),thermalgravimetric analyse(TGA),the thermal property of Na-montmorillonite(Na-mont) and organomontmorillonite(OM) was compared,the adsorption state of intercalated cations in the layer of organomontmorilllonite was investigated.
