1、Special surfactants and functional surfactants(Ⅲ)--Preparation and properties of organic silicone surfactants
2、Inhibition effect of several surfactants, and coordination inhibition effect of the surfactants and (CH2) 6n4 in hydrochloric medium were studied.
3、The rules of different kinds of betaine and macromolecule additives were simply concluded. In addition, the optimal prescription of these surfactants included nonionic surfactants was suggested.
4、The effect of surfactants on the uptake of pesticides depends on the structure (hydrophobe and hydrophile moieties) and concentration of the surfactants.
5、To develop affordable surfactants and oil displacement systems is the key.
6、PPL is a viscous emulsion prepared with a modified cellulose and several surfactants.
7、This system consists of bentonite, mixed metal hydroxide, cationic polymer and non-ionic surfactants etc.
8、The synthesis and performance of dimeric surfactants couple octanol sufisuccinate sodium
9、A new multifunctional diesel additive was developed by mixing surfactants, oily solvent and water, etc.
10、Measurements of the Chemical Oxygen Demand and the concentration of the anionic surfactants were used to follow the oxidation.
11、Application of surfactants was introduced in detail to manufacture superfine powder, sieve and porous material in this paper.
12、Effect of fluorocarbon surfactants on anti-solubility and anti-burning performance of hollow microsphere three-phase foam
13、The synthetic method is novel in the direct synthesis of amide surfactants by vacuum-amphoteric method without ring closing reactions.
14、Ineffective processing and disposal of oils, grease, petroleum hydrocarbons, surfactants or solvents used in vehicle washing and degreasing degrade surface water (AAPA, 1998).
15、Pyrene fluorescence probe was used to investigate the structure of the adsorbed layer of cationic surfactants primary amines and quaternary amines at the diaspore-water interface.
16、Their structures were confirmed by IR, and the properties of these surfactants such as acid number, interfacial tension, and critical micelle concentration and so on were studied.
17、Based on the summery of research findings by the predecessors, the invention is novel in direct synthesis of amide surfactants by vacuum-amphoteric method without ring closing reactions.
18、Oil - displacement surfactants OCS - 1 and OCS - 2 were prepared using vacuum residual oil from Daqing and Dagang as raw material respectively.
19、It has good biodegradation, low of cloud point, strong ability of resisting hard water, good lather ability and stability, little thrill to the skin, good cooperate with other surfactants and so on.
20、The tests show that the surfactants have good behaviour in floatation, and have advantages, such as good collective power, high selectivity and saving oil , so they have good prospect.
21、The polarographic catalytic waves of organic compounds, such as protein, flavone, steroide, quinine, α, β-unsaturated carbonyl compound, nitrogen-containing substances and charged surfactants, and their application are briefly introduced.
