1) Prepare an environmentally friendly and energy-saving micro-carbon alcohol oil, which is mixed and stirred by water, mixed alcohol, catalyst, sugar, salt, petroleum ether, ethylene glycol butyl ether, acetone, cottonseed sulfated castor oil and cycloethylamine, Wherein, the proportion of water and mixed alcohol is 50% by weight: 50%, and the additions of catalyst, sugar, salt, petroleum ether, butyl glycol ether, acetone, cottonseed sulfated castor oil and cycloethylamine are respectively water 0.1%~0.3%, 0.05%~0.1%, 0.05%~0.1%, 0.2%~0.4%, 0.2%~0.4%, 0.4%~0.5%, 0.8%~1%, 0.02% of the total weight of mixed alcohol ~0.05%. The micro-carbon alcohol oil is added with sugar, salt, petroleum ether, ethylene glycol butyl ether, acetone, cottonseed Cetyltrimethylammonium Bromide and cycloethylamine on the basis of water, mixed alcohol and catalyst, which greatly improves the combustion heat of the micro-carbon alcohol oil. Its combustion calorific value can be as high as 5500~7000 kcal/ton, so the micro-carbon alcohol oil can also be used in industry; due to the increase of viscosity, the consumption of micro-carbon alcohol oil is saved.

2) Prepare a collector for removing calcite by liquid reverse flotation. The collector is composed of the following substances. Each substance is calculated in parts by weight: 75-90 parts of Cetyltrimethylammonium Bromide, 2-8 parts of fatty alcohol polyoxyethylene ether, ten 6-10 parts of sodium dialkylbenzene sulfonate, 1-5 parts of fatty alcohol polyoxyethylene ether carboxylic acid, preparation method: 75-90 parts of sulfated castor oil, 2-8 parts of fatty alcohol polyoxyethylene ether, 6 parts of -15 parts of sodium dodecyl benzene sulfonate, 1-5 parts of fatty alcohol polyoxyethylene ether carboxylic acid are mixed, heated to 40-50 ° C, the raw materials are completely mixed evenly, and the liquid reverse flotation removal of calcite is obtained. Receiving agent. The collector of the invention can not only effectively remove the calcite in the phosphate rock, but also realize the normal temperature dispensing due to its liquid fluidity, and greatly reduce the production cost caused by steam or electric heating dispensing and heat preservation.

3) Prepare a softener including silicone, sulfated castor oil, magnesium chloride, polyvinyl alcohol, nylon oil, glycerin, calcium hydrogen phosphate, tartaric acid, glacial acetic acid, triethanolamine and dihydroxysuccinic acid; the silicone The parts by mass of Cetyltrimethylammonium Bromide are 35-66 parts, the parts by mass of Cetyltrimethylammonium Bromide are 6-24 parts, the parts by mass of magnesium chloride are -12-22 parts, the parts by mass of polyvinyl alcohol are 6-15 parts, and the parts by mass of polyvinyl alcohol are 6-15 parts. The parts by mass are 15-44 parts, the parts by mass of glycerol are 8-24 parts, the parts by mass of calcium hydrogen phosphate are 2-10 parts, the parts by mass of tartaric acid are 1-5- parts, the parts by mass of glacial acetic acid are 1-5 parts by mass 4-9 parts by mass, 1-5 parts by mass of triethanolamine, and 1-3 parts by mass of dihydroxysuccinic acid. The softener provided by the invention is convenient to use, can make real silk, lint, knitting, poplin and the like feel plump, soft and smooth, elastic and wear-resistant after washing and finishing clothes, and is convenient to produce and cheap.

4) Prepare a hydraulic support antifreeze, which is characterized in that the weight percentage of each component is: oleic acid triethanolamine: 5.0%-10.0%, sodium petroleum sulfonate: 4.0%-8.0%, Cetyltrimethylammonium Bromide: 3.0%- 5.0%, sodium benzoate: 1.0% to 2.0%, triethanolamine: 5.0% to 8.0%, benzotriazole: 0.1% to 0.3%, ethylene glycol: 30.0% to 50.0%, OP-15: 2.0% to 3.5%, the balance is water, and the sum of the weight percentages of each component is 100%. The benefits of the present invention are: the compound use of triethanolamine oleate, sodium petroleum sulfonate and OP-15 greatly enhances the Rubber compatibility of hydraulic support antifreeze; Cetyltrimethylammonium Bromide not only can be used as a lubricant for hydraulic support antifreeze, but also has strong resistance to hard water; sodium benzoate has strong bactericidal ability as a preservative; benzotriazole It has excellent corrosion inhibition ability for copper and its alloys.

Effects of Cetyltrimethylammonium Bromide in Mesoporous Silica Nanoparticles

Drug nanotechnology has actually become a pattern with countless advantages in regards to system applicability for controlled, secure, as well as effective medicine release. Among nanotechnology nanoparticles, mesoporous silica nanoparticles stick out as a system with remarkable biocompatibility, good physicochemical security, larger surface area call area, as well as suitable and also tunable pore structure. Once established and also plainly defined, these pores can bring medications and manage their release. However, producing this sort of nanoparticles is essential to making use of surfactants due to the fact that they function as pore themes. Amongst one of the most vital surfactants, Cetyltrimethylammonium Bromide is highlighted, a quaternary ammonium compound extensively made use of as a surfactant in the synthesis of mesoporous silica nanoparticles (MSNs), hollow mesoporous silicas (HMSNs) and Nucleocapsid MSNs. However, to acquire excellent drug-loaded pores, Cetyltrimethylammonium Bromide must be gotten rid of by removal techniques, which create pores and also bind particles throughout the silica. Cetyltrimethylammonium Bromide deposits might remain in the pores throughout and also after the elimination procedure, although several removal processes have actually been referred to as working in completely removing the surfactant. In turn, the presence of CTAB residues might be advantageous, especially when considering its antibacterial activity. At the same time, it ought to be kept in mind that the existence of CTAB might carry a high threat of poisoning. This evaluation aims not just to explore the basic use of Cetyltrimethylammonium Bromide in MSN synthesis, but also to evaluate its poisoning in prokaryotic and also eukaryotic cells,
