manufacture example 1
[0070] (Production Example 1S-(3-aminopropyl)thiosulfuric acid (amphoteric compound A))
[0071] Into a reaction vessel purged with nitrogen, 75 g of 3-bromopropylamine hydrobromide, 85.26 g of sodium thiosulfate pentahydrate, 375 ml of methanol, and 375 ml of water were added, and the mixture was refluxed at 70° C. for 5 hours. After standing to cool, methanol was removed under reduced pressure. 13.68 g of sodium hydroxide was added to the residue, and after stirring at room temperature for 1 hour, the solvent was removed under reduced pressure. 600 ml of ethanol was added to the obtained residue, and the mixture was refluxed for 1.5 hours. After hot filtration, the filtrate was concentrated under reduced pressure to obtain crystals. The crystals were taken out by filtration, washed with ethanol, and further washed with hexane. The obtained crystals were vacuum-dried to obtain S-(3-aminopropyl)sodium thiosulfate. 52 g of S-(3-aminopropyl) sodium thiosulfate, 90 ml of wate...
manufacture example 2
[0074] (Production Example 2S-(6-aminohexyl)thiosulfuric acid (amphoteric compound B))
[0075] Into the reaction container, 99.2 g of potassium phthalimide and 480 ml of dimethylformamide were added. A mixture of 200 g of 1,6-dibromohexane and 200 ml of dimethylformamide was dropped into this mixture at room temperature. After completion of the dropping, the obtained mixture was heated up to 120° C. and refluxed for 5 hours. After standing to cool, the solvent was distilled off from the reaction mixture. After adding ethyl acetate and a water solution, the organic layer was concentrated. Hexane and ethyl acetate were added to the obtained residue to precipitate crystals. The crystals were taken out and dried under vacuum to obtain N-(6-bromohexyl)phthalimide.
[0076] Add 40 g of N-(6-bromohexyl) phthalimide, 32.0 g of sodium thiosulfate pentahydrate, 200 ml of methanol, and 200 ml of water into the reaction vessel, and reflux the mixture for 5 hours. Distilled off from t...
