The researches on the stability of the compound system and the strong base, wastage of the agents in the oil phase and effects of the alkali, surfactant and polymer on the lactescence stability are conducted through collecting and analyzing the crude oils from the target layers of Lamadian, Saertu, Xingshugang Oilfields and so on. The study results show that the crude oil from Lamadian Oilfield has the characteristics of rather higher viscosity, higher paraffin content and higher gel content, and moreover the more kinds and quantities of the acid active components. The lactescence stability is pretty, higher and the wastage of the alkali in the oil phase is larger; with the higher content of the heavy components and wider range of the carbon chains, the wastage of the heavy alkyl benzene sulfonate surfactant in the crude oil is larger and the stability of the lactescence is higher; the single-base liquid acts with the oil and generates W/O-type emulsion, while the binary composite system of “alkali/surfactant” and ternary compound system of “alkali/surfactant/polymer” produce O/W-type emulsion. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8SDS of cas: 1731-94-8).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.SDS of cas: 1731-94-8
