The crystallization inhibitor can change the crystallization process of salt in a solution to the greatest extent, so that crystal lattices of salt crystallization are distorted, tiny salt crystallization particles cannot be normally enlarged, and meanwhile, the salt crystallization particles become small and coating layers with the same charges are formed among crystal grains through the surface tension reduction and coating effects of the surfactant, the formation of large-particle salt crystals is inhibited through the principle that like poles repel each other, the formation of large-particle crystal salts in the salt-containing wastewater is inhibited, the operation cycle of a quench tower and a multi-effect evaporator of a hazardous waste incineration system is prolonged, and the production efficiency is improved.

The invention relates to a 4-carboxylphenyl retinamide ethanol compound, a preparation method thereof, and a medicinal composition and application thereof. The structural formula is shown as the specifications.

The invention discloses a preparation method of a corrosion-resistant paint used for outer steel plates of ships or automobile shells and capable of resisting erosion resulting from seawater, rainwater or the like.According to a preparation method, stearic acid sodium salt is mainly used for subjecting Al2O3 to surface lipophilic treatment so as to prepare the Al2O3 modified corrosion-resistant paint.The preparation method has the advantages that the stearic acid sodium salt is selected as a surface modification material, hydrophilic and hydrophobic groups similar to coupling agents exist in SASS (stearic acid sodium salt) molecules, and through experimental verifications, after coating treatment of the stearic acid sodium salt, nano-Al2O3 and film-forming matter affinity is enhanced, so that interface bonding force of the film-forming matter is enhanced; hard aggregation forming can be stopped or relieved, good dispersity can be obtained easily, and accordingly mechanical strength of paint coatings is improved and adhesive force is remarkably enhanced.

The invention discloses repairing soup with abrotani herba and gingko as raw materials and a making method of the repairing soup and belongs to the technical field of healthcare foods. The making method comprises the following steps: S1, respectively cleaning and sterilizing abrotani herba, gingko leaves, glottiphyllum linguiforme, licorice roots, coral dealbatus and ginkgo seeds, putting the rawmaterials into a pot, adding water, and performing mixing and boiling; S2, after the water in the pot of the step S1 is boiled, adding lotus seeds, and continuously boiling the raw materials for 2-4 hours; S3, putting the ginkgo seeds and the lotus seeds in the pot into a clean container for later use, further filtering the mixture left in the pot, removing residues so as to obtain filtrate, putting the ginkgo seeds and the lotus seeds in the clean container into the filtrate, and continuously performing temperature keeping and heating on the raw materials; S4, adding honey and rock candy intothe mixture finally heated in the step S3, melting the honey and the rock candy, and further gradually adding white granulated sugar into the mixture to adjust the taste; and S5, stopping heating, and reducing the temperature of the mixture to 50-60 DEG C for eating. The repairing soup has good effects of activating blood, removing toxins and improving memory abilities.

A process for the fluid catalytic cracking of oxygenated hydrocarbon compounds from biological origin. The process comprises contacting a feed comprising the oxygenated hydrocarbon compounds from biological origin and an amount of sulphur with a fluid cracking catalyst at a temperature of equal to or more than 400° C. to produce a products stream. The process further comprises separating fluid cracking catalyst from the products stream and separating a light fraction from the products stream; and removing hydrogen sulphide from the light fraction by means of an amine treating process. Activated carbon is used to treat at least part of an amine solution used in the amine treating process or to treat at least part of the feed to the amine treating process.

A microbial adherence inhibitor in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment of adherence of colony-forming immunogens in the respiratory tracts of host animals and humans. The inhibitor is made by inoculating female birds with the immunogen, harvesting the eggs which contain antibodies to the immunogen, and separating the yolk and albumin from the shells of the eggs. The yolk and albumin contents are administered to animals or human by distributing the contents directly or introducing the contents entrained in air. The adherence inhibiting material can be formulated for use in a variety of ways such as an oral spray or a nasal spray. These formulations can be effective to prevent or reduce respiratory illnesses in animals and humans.
