An odor absorbing composition is provided comprising zinc salt of ricinoleic acid, a solubility promoter including sodium iminodisuccinate, water and optionally, other ingredients such as perfumes and antifungal agents or bactericides. The zinc ricinoleate can be completely solubilized in water, yet the solution will exhibit low foaming and friability. In addition, the end product may be in the form of a sprayable liquid, a thick liquid capable of clinging to a vertical surface, a gel or solid tablet, a powder, or any other form. The present invention further relates to a method for forming an odor absorbing composition comprising zinc salt of ricinoleate acid, sodium iminodisuccinate and water.

The invention discloses the application of iminodisuccinate as a fertilizer synergist. The iminodisuccinate is added to a basic fertilizer as a fertilizer synergist, and the basic fertilizer does not contain trace element supplements. As a fertilizer synergist, iminodisuccinate can activate a variety of fixed metal ions in the soil so that they can be absorbed by crops, without adding supplements containing trace elements, which reduces the The production cost and sales price reduce the burden on farmers; at the same time, the metal ion content in the soil is reduced, which effectively improves the problem of soil compaction caused by the large-scale application of fertilizers.

The invention discloses a synthesis technology of a chelating agent-tetrasodium iminodisuccinate. The tetrasodium iminodisuccinate is obtained through atmospheric production of fumaric acid, ammonium bicarbonate and sodium hydroxide as raw materials. The preparation method is simple, convenient, low in cost and stable in effect; the obtained etrasodium iminodisuccinate is good in quality and high in purity, does not contain toxic substances such as fumaric acid, can be directly mixed with various fertilizers and is used as a fertilizer enhancing chelating agent.

The invention provides a neutral cleaning agent for motor trains and a preparation method thereof. The neutral cleaning agent for motor trains consists of the following components by weight: 4 to 6 parts by weight of anionic surfactants, 8 parts by weight of nonionic surfactants 12 parts by weight, 6 parts by weight to 10 parts by weight of complexing agent, 0.5 parts by weight to 2 parts by weight of dispersant, 3 parts by weight to 8 parts by weight of pH regulator, 62 parts by weight to 78.5 parts by weight of deionized water, Anionic surfactants include alcohol ether carboxylate AEC and fatty acid methyl ester sulfonate, and complexing agents include sodium iminodisuccinate and trisodium methylglycine diacetate. The EMU neutral cleaning agent can effectively remove yellow spots, water marks, dust and oil stains on the outer surface of the high-speed rail, and solve the problems of corroding the car body, polluting the environment, and endangering health in the cleaning process of existing cleaning agents.

The invention relates to a modification method of chitin fiber and its application. Aiming at the problem of poor adsorption performance of ordinary chitin to metal oxides, it provides a one-step preparation method of modified chitin fiber for shrimp shells and its application. First, the shrimp The shells are dried, pulverized and sieved to obtain shrimp shell powder, and then an aqueous solution of sodium iminodisuccinate, potassium persulfate and hydrogen peroxide are added to the shrimp shell powder to obtain modified chitin fibers. The method directly prepares the modified chitin fiber in one step without treating the shrimp shell with acid, alkali or ethanol, and the process is simple, and the reagent consumption is reduced. To apply the product to the preparation of flexible materials, the modified chitin fibers are ultrasonically treated with acetic acid solution and then centrifuged to obtain a supernatant; then the supernatant is diluted with deionized water and evaporated to dryness to obtain a flexible material. The enhanced adsorption capacity of chitin to metal oxides after modification is beneficial to the coating of flexible materials with metal oxide layers, thereby increasing the properties of the substrate such as transparent conductivity, piezoelectricity, photoelectricity, and gas sensitivity.
