The invention relates to the technical field of organic silicon resin preparation, in particular to trapezoidal methyl silicon resin and a preparation method thereof.The trapezoidal methyl silicon resin is prepared by taking methyl trichlorosilane as a main raw material, introducing a trapezoidal control agent containing amido and alkoxy at the same time to inhibit the reaction activity of the methyl trichlorosilane and then carrying out hydrolysis reaction in a small amount of alcohol solvent and water; the generation of a cross-linked network structure insoluble substance during hydrolysis is avoided, and the resin gelation risk is effectively reduced. The hydrolysis rate is reduced, so that the use amount of the solvent is reduced, the proportion of alcohol in the water phase is greatly reduced, and the process and environmental protection cost is reduced. The trapezoidal methyl silicone resin prepared by the method is excellent in viscosity performance, high in yield, excellent in boiling resistance, short in curing time, high in resin softening point and short in gelation time.

The application discloses a catalyst for synthesizing glycine and application of the catalyst in preparation of glycine, and relates to the technical field of glycine production. In the reaction process, one or more polymerization inhibitors are selected and the addition amount is controlled, so that the amount of formaldehyde is controlled to be reduced, the catalyst consumption is reduced, the catalyst consumption is reduced, and the glycine yield is improved.

This invention discloses a seawater treatment system for aquatic organism seedling and larval cultivation based on a natural ecological cycle. The system includes a natural sedimentation tank, a secondary sedimentation algae cultivation tank, a multi-stage dark sedimentation tank, a primary sand filter, a secondary sand filter, and a water storage tank connected to the end of the secondary sand filter. A pump is installed to connect to a water storage tower. A seawater concentration device and an ultrafiltration device are also included between the water storage tower and the aquatic organism seedling tank. The secondary sedimentation algae cultivation tank can be directly connected to a juvenile shellfish rearing tank for direct use in juvenile shellfish cultivation. The sand filter also features a backwashing design for easy recycling. The seawater processed through the primary and secondary sand filters, concentration device, and ultrafiltration device can be used for larval cultivation of aquatic organisms. This water treatment system, through its multi-stage structural design and combined with natural environmental control of light and shading, avoids the drawbacks of chemical and biological purification and the shortcomings of simple physical sand filtration in a natural and ecological way. This ensures a large-scale supply of water for aquatic organism seedling and shellfish cultivation, meeting the diverse needs of large industrial areas.
