3447 results about "Oleic Acid Triglyceride" patented technology

Instead fatty acids like oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Fatty acids can be obtained by the saponification of triglycerides. Triglycerides of oleic acid comprise the majority of olive oil. Free oleic acid render olive oil inedible.

High-yield preparing method for inorganic halogen perovskite fluorescent quantum dots at room temperature

The invention discloses a high-yield preparing method for inorganic halogen perovskite fluorescent quantum dots at the room temperature. The fluorescent quantum dots are CsPbX3, wherein X is equal to AxB1-x and is larger than or equal to 0 and smaller than or equal to 1, and A and B are any one of Cl, Br and I. The method comprises the following steps that firstly, lead halide and cesium halide are dissolved into dimethyl formamide, surfactant oleylamine and oleic acid are added, the mixture is stirred until complete dissolution, and a precursor solution is obtained; secondly, the precursor solution is dripped into a poor solvent at the speed of 0.08-0.13 mL/s and stirred evenly at the uniform speed, and the inorganic halogen perovskite fluorescent quantum dots CsPbX3 are obtained. The preparing method is implemented at the room temperature, protection gas is not needed, equipment is simple, mass production can be achieved, and full visible light band shining can be achieved by selecting halogen and adjusting the proportion of halogen. The full width at half maximum of the inorganic halogen perovskite fluorescent quantum dots prepared through the preparing method ranges from 16 nm to 39 nm, the fluorescence quantum efficiency is close to 90%, and the inorganic halogen perovskite fluorescent quantum dots can be stably stored for more than three months, and can be used in the field of solar cells, lasers, light detectors, light-emitting diodes and the like.

The invention discloses a preparation method of grease with a humanized structure. The preparation method comprises the following steps: carrying out intra-molecular rearrangement reaction to palm oil with palmitic acid content of higher than 50% under the action of catalyst to obtain Sn-2 locus triglyceride with palmitic acid content of higher than 50%; and carrying out ester exchange reaction to the Sn-2 locus triglyceride with palmitic acid content of higher than 50% with mixed fatty acid or non-glyceride under the action of 1,3 locus Specificity lipase, and then subjecting the reaction product to after treatment, so as to obtain the grease with humanized structure, wherein the mixed fatty acid is mixture of at least two selected from the group consisting of decanoic acid, lauric acid,myristic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid and linolenic acid. The vegetable oils are used as the raw material according to the method, so the safety is high; the preparation process is simple, the reaction time is short, the enzyme dosage is low, and the cost is low; and the prepared grease with the humanized structure is very similar to the beast milk fat in the composition of fatty acid and the structural distribution of triglyceride, so the grease can be added in infant formula or formula foods and used as breast milk fat substitute.

Rubber modified asphalt warm-mixing agent, preparation method and application

The invention discloses a rubber modified asphalt warm-mixing agent, a preparation method and application thereof. The warm-mixing agent comprises the following components in parts by weight: 100 parts of water, 5-30 parts of fatty alcohol sodium sulfate, 15-30 parts of palmitic acid, 5-30 parts of oleic acid, 1-20 parts of sodium dodecyl benzene sulfonate, 1-15 parts of cetyltrimethylammonium chloride and 10-30 parts of imidazoline-type cationic surface active agent ODD. The preparation method comprises the following steps of: adding the water in a container at the temperature of 65 DEG C, and then adding the following substances under the condition of stirring: the fatty alcohol sodium sulfate, the palmitic acid, the oleic acid, the sodium dodecyl benzene sulfonate, the cetyltrimethylammonium chloride and the imidazoline-type cationic surface active agent ODD, and stirring for 15 min to obtain the warm-mixing agent. The warm-mixing agent is directly applied to rubber asphalt or matrix asphalt to reduce the viscosity of the asphalt. The kinematic viscosity of the rubber powder asphalt added with the warm-mixing agent at the temperature of 150 DEG C can reach less than 3.0Pa.s of the kinematic viscosity at the temperature of 180 DEG C, and the production temperature can be reduced by about 30 DEG C, thereby not only preventing the rubber asphalt from being aged but also saving energy and reducing equipment loss.
