When the water concentration is lower than the lower limit, it is not preferable because the hydrochloric acid concentration of the aqueous solution of the zirconylphosphonic acid is '‘ίί phosphine. When the water concentration is higher than the range, the rate of sputum is greatly impaired, which is less desirable. In the present invention, when the concentration of the water of the amine is outside the range, it is required to be within the range of the aqueous solution, and on the premise of this, by "the amount of water" And obtaining a high-purity amino group to increase or decrease the concentration of the f f f _ acid aqueous solution of the = = = = = = = = , , , , , , , , , , , , , , , , , , , , The ideal state is 1 to 12% by weight, and more preferably 1 to 9 5 wii. The concentration of the methylene phosphonic acid in the aqueous solution of the capped crude aminomethylphosphonic acid is not limited, but Preferably, the mixture is 1〇~5〇 straight % 〇 (manufacture of aqueous solution of crude amino sulfinylphosphonic acid). In the present invention, the aqueous solution of crude aminomethylenephosphonic acid is preferably acidic under hydrochloric acid or amine and Formaldehyde and phosphonic acid are obtained by reaction. When the aminomethylenephosphonic acid is used in the semiconductor industry, it is not suitable to use a metal such as galvanized steel, which is available in the form of a metal, which is a metal lining (hereinafter referred to as GL). Into: a mixer-type reaction that is not mixed. Dad is more reasonable: (3) 蚤 beforehand, it is made into a clean state in which the metal component such as Fe does not dissolve, and S is made. The method of purifying and purifying is _ Wei Wei, go to Xuan Shui cleaning. The following is a more illustrative example of a preferred order of preparation. First, hydrochloric acid is added to the GL kettle, followed by the addition of squaric acid, which is heated by the reaction with hydrochloric acid by the addition of the sub-disk acid, and is heated; the temperature is maintained at 5 to 15 t:. Next, the reaction temperature is maintained at 15 to m:, and ammonia or an amine is added at a constant rate. Since this reaction is released, heat dissipation is required. After the end of the amine addition I, the reaction solution was heated to 85 to 95 t:. Next, 35 to 50% by weight of formalin is supplied at a constant rate to carry out the reaction. The reaction itself is an exothermic reaction, and the temperature at which the reaction stays up late is managed to be 9 〇 1 〇 (rc. After the reaction is completed in 201219411, it is cooled to -temperature and ends as a reaction. The generated hydrochloric acid vapor is based on the anti-pollution using reflux. The viewpoint is turned over to the outside by spraying the material, and avoiding the reflux as much as possible, and treating it with the exhaust gas treatment equipment. Among the series of operations, the focus is on the need to inject t, Kecheng silk. The scale is said to lay the Wei Qing. Very important. = In the reaction, the preferred form of the amine can be exemplified by ethylenediamine, hydrazine, 2_-propylenediamine, hexamethylenediamine, diethylenetriamine, etc. Phosphorous acid, the preferred state is: 3 to 6 times the molar amount of N atoms; in the case of the amine, the amine is 2 to 4 times the molar of n ^ 2, and the secondary amine is 1 to 2 times the molar of the N atom. In the case where the amine has a primary and secondary amine moiety in one molecule, the sum of the respective amounts used for the previous primary and primary amines can be used. In the reaction, the preferred form of formaldehyde is: when ammonia is used Using 3 to 9 moles of N atom, when using an amine, the amine is a primary amine In the case of using 2 to 6 moles of N atom, the case of secondary amine is 丨3 to 3 moles of N atom. In the case where the amine is a hydrazine molecule, there are amines of primary and secondary, which can be used for the previous The sum of the respective amounts of the primary and secondary amines. The preferred form of the acid is a mineral acid such as phosphoric acid or nitric acid. & melon® 夂 [steamed aqueous solution of crude aminomethylenephosphonic acid Gu!] A crude amine-based methylene phosphonic acid aqueous solution containing furfural, in order to remove residual formaldehyde, is distilled by a batch distillation apparatus, and the crude amine-methylene phosphonic acid is water-soluble, water, The degree is required to be 35 to 60% by weight, and when the concentration of water is outside the range, water is added before the distillation, and the mixture is allowed to be in the bacteria as described above. The batch distillation apparatus used in the present invention will be described below. An example of the batch type retorting apparatus of the present invention includes a distillation apparatus including a distillation pot and a condenser. The material of the & distillation apparatus is made of glass. The distillation temperature is preferably 90 to 120 ° C, and is preferable. The state is 1〇〇~. Furthermore, in the present invention, due to the crude: amine group in the distillation_ The addition of water to the aqueous solution of phosphinic acid allows the formaldehyde to be efficiently distilled off under normal pressure, so that the equipment modification cost of the product is not required to be adjusted, and it is also advantageous in terms of safety surface, and is very industrially beneficial. [Addition of water] 201219411 * In the present invention, it is important to add water to steaming hydrazine in the distillation. In the present invention, an aqueous solution of a nonaminylphosphonium acid containing furfural is added to the distillation pot, and the distillation still is heated to form a component. Distilled from the distillation column, condensed by a condenser, and measured by a supersonic flow, or a counter of a vortex flowmeter, etc., and more preferably, it is repeatedly prepared in distillation. Adding the same amount of water as the amount of the distillate to the distillation kettle, H is added to the same amount as the mixed water, and it is preferable to pay attention to not to make the inside of the distillation pot thick. The temperature of the aqueous solution of the aminomeridenephosphonic acid is decreased by - while being rapidly added. 5〜1.5倍。 The amount of the amount of the library is 0. 5~1.5 times the amount of the library. The range, the more ideal form is 〇. 2, ^ circumference 'more ideal form is G · 9 ~ 1.1 times the face, and the most ideal form is undoubtedly completely equal. Further, the measurement of the amount of the distillate may be carried out immediately depending on the size of the distillation apparatus or the energy of the condenser, or may be carried out at intervals of 30 to 60 minutes. In the water added by the distiller, it is more reasonable to use ion-exchanged water for the purpose of preventing metal contamination. 4, if the quality of the metal is stable, distilled water can be used. In the present invention, the total amount of water added to the distillation pot in the distillation is 0.5 times the added weight of the aqueous solution of the aminomeridenephosphonic acid. Since the amount of the present invention is at least G. 5 times 4, a highly pure aminophosphonium phosphonic acid can be obtained. The Japanese type _ adds water equivalent to the amount of the liquid in the fine to the steaming 蚤. Therefore, it is not necessary to add the water in the addition of the aqueous solution of the crude amide thiolphosphonic acid, and it is very industrially advantageous. ,,,,,,,,,,,,,,,,,,,,,,
