2321 results about "BENZYL ALCOHOL/WATER" patented technology

Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether. The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide.

Preparation method of homogenized fine nano-cellulose fiber

The invention relates to a preparation method of a homogenized fine nano-cellulose fiber. The preparation method can solve the problems of uniform diameter distributor of biomass nano-cellulose prepared by the existing strong acid hydrolysis method and the high-strength mechanical shearing method, easy gathering among the nano-fiber and a narrow range of applications of the TEMPO catalytic oxidation method. The preparation method comprises the following steps: 1) extracting biomass fiber with benzyl alcohol solution; 2) carrying out treatment by using acidified sodium chlorite; 3) carrying out gradient treatment with alkaline liquor; 4) using TEMPO, sodium bromide and sodium hypochlorite for catalytic oxidation treatment; 5) using sodium chlorite for treatment; and 6) carrying out nano-scale processing by using the long-term stirring method, the ultrasonic method or the high-pressure homogenization method, drying, and then obtaining the homogenized fine nano-cellulose fiber. The fiber has the uniform diameter distribution, the diameter is 3-5nm, the length-diameter ratio is not less than 500, the fiber is mutually interwoven into a mesh snarling structure, and the method is applicable to preparing the nano-cellulose fiber by using wood pulp, paper-making pulp, wood, bamboo and crop straw.

Method for preparing molybdenum disulfide (MoS2) nanosheet

The invention discloses a method for preparing a molybdenum disulfide (MoS2) nanosheet by two steps, namely a hydrothermal method and a liquid phase ultrasonic stripping method. The method disclosed by the invention is realized by the following technological steps: evenly mixing the bought MoS2 powder with lithium carbonate according to the molar ratio of 1: 42, putting the mixture into a high pressure kettle filled with 40ml of benzyl alcohol, and sealing; maintaining for 48 hours at the temperature of 200 DEG C; carrying out natural cooling and vacuum drying to obtain an intermediate product; putting 0.2-0.6g of intermediate product into mixed liquid of 20ml of dimethyl formamide and 10ml of water, and carrying out ultrasonic dispersion for 12 hours; centrifuging the obtained dispersed liquid for 30-45 minutes at the speed of 500-600rpm (revolutions per minute), and then centrifuging the supernatant liquid for 6 minutes at the speed of 6000-8000rpm; cleaning the product by 3% HCl for twice, and then cleaning the product by deionized water until the product is neutral; and finally, carrying out vacuum drying on the product to obtain the nano MoS2 sheet. The MoS2 nanosheet is stripped by the method disclosed by the invention. The method has the characteristics of being simple, easy to realize and popularize and suitable for large-scale industrial production.

Real-stone paint and preparation method thereof

The invention relates to real-stone paint and a preparation method thereof and belongs to the technical field of building decorative materials. Firstly, an inorganic mineral rheological agent and a nonionic water-soluble cellulose ether are combined, so that the two components have the synergistic effect of guaranteeing viscosity of the real-stone paint and excellent constructability, and on the basis hereinabove, the usage amount of cellulose ether, which has water retention effect, in the real-stone paint is reduced, so that a paint film is reduced in the water retention effect and moisture volatilization is improved; secondly, alcohol ester-12 is combined with any one of four film forming additives, comprising ethylene glycol monobutyl ether, propylene glycol butyl ether, diethylene glycol butyl ether and benzyl alcohol, which have high volatile speed, thus accelerating film forming. For solving of a problem of poor antifouling performance of the real-stone paint, through reasonable combination of particle size of color sands and usage of a hydrophobic agent, the real-stone paint can form a compact film and a nano hydrophobic coating layer, which is completely composed of nano hydrophobic particles, is formed on the surface of the paint film, so that the paint film is reduced in surface energy and water absorbency, and is improved in antifouling performance.
