  • Low sulfur diesel blockage inhibitor, preparation method therefor and use thereof
    Patent number: 11912657
    Abstract: A low sulfur diesel blockage inhibitor as shown in formula (I), a preparation method therefor, and use thereof are provided. In formula (I), x and y are each an integer between 0 and 4; m and n are each selected from H, a C1-C6 linear or branched alkyl group, or a C3-C6 cycloalkyl group. By using a vegetable oil as a raw material, a modified vegetable oil fatty acid is first obtained, and then a polar group of an unsaturated dialdehyde with a certain chain length is introduced into a molecular chain of the modified vegetable oil fatty acid.

  • LIQUID-LIQUID MIXER, LIQUID-LIQUID REACTION APPARATUS COMPRISING LIQUID-LIQUID MIXER, AND LIQUID-LIQUID REACTION METHOD USING LIQUID-LIQUID MIXER
    Publication number: 20240024830
    Abstract: The present disclosure provides a microchannel liquid-liquid mixing device, comprising a microchannel component and a shell, wherein the microchannel component is fixed inside the shell, wherein an inlet is provided at one end of the shell for feeding at least two reaction liquid phases, and an outlet is provided at the other end for discharging a mixed material; said microchannel component comprises multiple stacked sheets and oleophilic fiber filaments and hydrophilic fiber filaments filled in the crevices between adjacent sheets, wherein the fiber filaments form several microchannels between them, and the fiber filaments are clamped and fixed by the sheets. The microchannel liquid-liquid mixing device is used for at least two reaction liquid phases to form a mixed material, and the at least two reaction liquid phases are cut by fiber filaments and mixed in the microchannel mixing device to form a mixed material.
