  • Patent number: 10844319
    Abstract: The present invention provides a fatty glyceride preparation method, comprising converting fatty acid short-chain alcohol ester into fatty glyceride basic mixture by sequentially carrying out a normal-pressure reaction and a vacuum reaction in the nitrogen condition in the temperature of 80° C. to 150° C.; and meanwhile adding a basic catalyst and glycerin or adding a basic catalyst and a glycerin derivative into the fatty acid short-chain alcohol ester, so as to implement a conversion from the fatty acid short-chain alcohol ester to the fatty glyceride. Conditions of the preparation method are relatively moderate, and the structure of the fatty acid is not damaged in the reactions; the yield of the glyceride is high, compositions of the glyceride are stable and controllable, glyceride products having a high content of triacylglycerol can be obtained; the process is simple, costs are low, and the fatty glyceride is applicable to industrial production.

  • Patent number: 10505636
    Abstract: The present invention relates to the field of mobile communications technologies. The methods for sending and receiving a signal are specifically: splitting a received digital signal into a first digital signal and a second digital signal, respectively converting the first digital signal and the second digital signal into an analog in-phase signal and an analog quadrature signal, respectively modulating the analog in-phase signal and the analog quadrature signal to two optical signals that are perpendicular to each other and are in a polarization state, combining, into one optical signal, the two optical signals that are perpendicular to each other and are in a polarization state, and sending the optical signal to an ONU; and performing, by the ONU, corresponding demodulation on the optical signal, and sending the optical signal to a user terminal.

  • Patent number: 10011550
    Abstract: A method for preparing high-content conjugated linoleic acid (CLA) through purification of vegetable oil includes alcoholysis, purification and isomerization of vegetable oil. Alcoholysis is for preparing corresponding methyl ester or ethyl ester with glyceride; purification of methyl ester or ethyl ester is for obtaining methyl linoleate or ethyl linoleate of content over 85% through silver-based silica gel column chromatography; high-content CLA is obtained after alkali-catalyzed conjugation of methyl linoleate or ethyl linoleate, and CLA products are prepared as needed. This invention changes the status quo of preparing high-content CLA with safflower oil alone, expands sources of CLA, and develops an efficient technology for separation and purification of linoleic acid. The CLA obtained is of high purity and meets applications in pharmaceutical, health care products and other industries.

  • Publication number: 20170240507
    Abstract: The present invention discloses a method for recycling urea in the process of separating and purifying unsaturated substances through a urea adduction method. The method comprises the following steps: liposoluble substances containing target unsaturated components are used as raw materials, and subjected to urea adduction, crystallization and filtration to produce a filtrate, from which the specific unsaturated components are obtained; the urea adduct is dissolved in a polar solvent, and after the adducted adducts are layered and released, adding a certain solvent to the urea solution to adjust the polarity, then cooling for crystallization, and recycling the urea.
