The new preparation method of Al-Ti-C grain refiner was studied with aluminium ingot,potassium hexafluorotitanate,aluminium powder,hexachloroethane and carbon powder.
Tetrachloroethane in air was collected by activated carbon,desorped with carbon disulfide,separated by GDX-103 chromatography column,and detected by flame ionization detector.
The amino-acid imidazoline amphoteric surfactant was prepared from dichloroethane and vegetable-oil fatty acid as raw materials by aminolysis, esterffication and hydroxymethylation.
Ethyl cellulose was synthesized successfully in one step based on reaction of cellulose with excess chloroethane and sodium hydroxide in toluene as diluent.
The proposed method was applied to extracting pure spectra and determining background of a two component system which consists of dichloroethane and propanone, satisfactory results were obtained.
