Preparation method of 3,4-dimethylammonium sulfonate_Kain Industrial Additive

Background and overview^[1]

3,4-Ammonium xylene sulfonate can be used in the pharmaceutical and chemical fields.

Preparation^[1-3]

Application examples of 3,4-dimethylammonium sulfonate are as follows:

1) Prepare a laboratory-specific detergent, which is composed of dodecylbenzene sulfonic acid, triethanolamine, 3,4-ammonium xylene sulfonate, fatty alcohol polyoxyethylene ether, EDTA-4Na, and hydrogen peroxide , sodium tetraborate, protease, activated carbon powder and other components to prepare a liquid detergent. The invention removes common stains during the washing process of laboratory glassware, such as metal oxides, insoluble metal ions, macromolecular esters, animal and vegetable oils, denatured coagulation proteins of various culture vessels for culture media, oily dirt, etc. They can be quickly removed, and have the advantages of being easy and safe to prepare and use, low cost, less corrosive to skin and instruments, and less environmental pollution.

2) Prepare a water-based printed circuit board cleaning agent, which is made from the following raw materials by weight: dodecylbenzene sulfonic acid 3-5, triethanolamine 1-2, 3,4-ammonium xylene sulfonate 2-3. Sodium dioctyl succinate sulfonate 3-4, ethanol 40-50, palmitic acid 1-2, disodium ethylenediaminetetraacetate 2-3, additives 4-5, deionized water 100-120 . The cleaning agent of the present invention has good permeability, can be cleaned without dead ends, has excellent cleaning ability against rosin, soldering flux, organic matter, and inorganic matter, has good corrosion inhibition effect, is low in cost, has no pollution to the environment, and is non-toxic to the human body. Suitable for cleaning a variety of circuit boards. The additive of the present invention can form a protective film on the surface of the circuit board, isolate the air, prevent water and other molecules in the atmosphere from corroding the circuit board, resist oxidation and short circuit, and facilitate the next step of the production process.

3) Prepare an oil for spray printing, which relates to the technical field of printing and spray printing. It is characterized in that: it is made of the following parts by weight of materials, 3-5 parts by weight of organic pigment, 4,4′-diphenylmethane di 2-3 parts of isocyanate, 10-12 parts of antioxidant, 1-3 parts of zinc phosphate, 2-3 parts of tributyltin trichloride, 10-13 parts of E-42 epoxy resin, 1-3 parts of sodium chloride phosphate 2-4 parts of triethanolamine borate, 2-5 parts of propylene carbonate, 4-7 parts of ethylene glycol, 3-6 parts of ammonium 3,4-xylene sulfonate, and 3-6 parts of zinc borate. The method of the invention is reasonable, the proportion is reasonable, and the operation is convenient.
