Sulphuretted Hydrogen

The investigations contained in this paper were undertaken with the view of ascertaining the nature of the action of sulphur in the free state on organic substances. The author endeavoured, in the first instance, to examine the action of that agent upon some of the simpler organic compounds, but without obtaining any definite results; and finally confined his experiments entirely to the fixed oils.The distillation of oil of almonds with sulphur, which is attended by the violent evolution of sulphuretted hydrogen, afforded a peculiar nauseous oil, and a crystalline product deposited on cooling from the latter portions of the oil. In order to ascertain the source of these products, comparative experiments were made with pure stearic and oleic acids. It was thus found, that stearic acid, when distilled with sulphur, gave products identical with those obtained by its simple distillation, but that oleic acid gave an oily fluid and crystals similar to those produced from the crude oil.

Soluble Surfactant

According to the mechanisms of carbon dioxide miscible flooding and previous researchers’ work on synthesis of CO2-soluble surfactant, Citric acid isoamyl ester was synthesized, and it’s oil solubility and the rate of viscosity reduction both in oil-water system and oil were evaluated. And then we found that this compound can solve in oil effectively; the optimum mass of Citric acid isoamyl ester introduced in oil-water system is 0.12g when the mass ratio of oil and water is 7:3 (crude oil 23.4g, formation water 10g) and the experimental temperature is 50°C , the rate of viscosity reduction is 47.2%; during the evaluation of the ability of Citric acid isoamyl ester to decrease oil viscosity, we found that the optimum dosage of this compound in 20g crude oil is 0.2g when the temperature is 40°C, and the rate of viscosity reduction is 7.37% at this point.
