Sulfamic acid Kushandiswa uye Synthesis
| Chemical Properties | Sulfamic acid is white orthorhombic flaky crystal, isina kunhuhwirira, isingavhurike uye isiri-hygroscopic.Soluble mumvura uye liquid ammonia, inonyungudika zvishoma mumethanol, isinganyunguriki mu ethanol uye ether, zvakare isinganyunguriki mucarbon disulfide uye liquid sulfur dioxide.Mushonga waro une aqueous wakaita asidhi yakasimba yakafanana nehydrochloric acid uye sulfuric acid, asi kuora kwayo kusimbi kwakadzikira zvakanyanya pane iyo yehydrochloric acid.Iyo chepfu idiki zvakanyanya, asi haifanirwe kunge yakabatana neganda kwenguva yakareba, uye haifanirwe kupinda mumeso. |
| Uses | Sulfamic acid inoshandiswa zvakanyanya mu electroplating, hard-water scale removers, acidic cleaning agent, chlorine stabilizers, sulfonating agents, denitrification agents, disinfectants, flame retardants, herbicides, artificial sweeteners uye catalysts. Sulfamic acid inotungamira kune zvinotapira-zvinonaka zvinosanganiswa.Kuita ne cyclohexylamine inoteverwa nekuwedzera kweNaOH inopa C6H11NHSO3Na, sodium cyclamate. Sulfamic acid inonyungudika mumvura, ine mwero yakasimba asidhi.Iyo yepakati pakati pe sulfuric acid ne sulfamide, inogona kushandiswa sefanotangira kune zvinotapira zvinonaka, mushonga unorapa chikamu, acidic yekuchenesa agent, uye catalyst ye esterification. |
| Application | Sulfamic acid, iyo monoamide ye sulfuric acid, inorganic acid yakasimba.Inowanzo shandiswa mumakemikari ekuchenesa maitiro sekubvisa nitrites, carbonate- uye phosphate-ine madhipoziti. Sulfamic acid inogona kushandiswa sechinhu chinokonzera mu: Friedlander quinoline synthesis. Liquid Beckmann rearrangement yekubatanidzwa kweamides kubva ketoximes. Kugadzirira kwea-aminophosphonates kuburikidza neatatu-chikamu chekuita pakati pealdehydes, amines, uye diethyl phosphite. |
| Tsanangudzo | ChEBI: Sulfamic acid ndiyo yakapfava yesulfamic acids inoumbwa neatomu imwe yesarufa yakasungwa zvakabatana nemabhondi ega kuhydroxy nemaamino mapoka uye nema bond maviri kumaatomu maviri eokisijeni.Iasidhi yakasimba, inokurumidza kugadzira sulphamate munyu, inonyungudika zvakanyanya mumvura uye inowanzovapo sezwitterion H3N+.SO3–. |
| Reactions | Sulfamic acid iasidhi yakasimba inopindirana nemakomisheni akawanda ekutanga.Inopisa kusvika pamusoro penzvimbo yakanyunguduka (209 ° C) pasi pekumanikidzwa kwemazuva ose kuti itange kuora, uye inoramba ichipisa kusvika pamusoro pe260 ° C kuti iparare kuva sulfur trioxide, sulfur dioxide, nitrogen, hydrogen uye mvura. (1) Sulfamic acid inogona kuita nesimbi kuita munyu unoonekera wecrystalline.Zvakaita se: 2H2NSO3H+Zn→Zn(SO3NH2)2+H2. (2) Inogona kuita nesimbi oxides, carbonates uye hydroxides: FeO+2HSO3NH2→Fe(SO3NH2)2+H2O2 CaCO3+2HSO3NH2→Ca(SO3NH2)2+H2O+CO23 Ni(OH)2+2HSO3NH2→Ni(SO3NH2)2+H2O. (3) Inogona kuita nenitrate kana nitrite: HNO3+HSO3NH2→H2SO4+N2O+H2O2 HNO2+HSO3NH2→H2SO4+N2+H2O. (4) Inogona kuita neoxidants (yakadai sepotassium chlorate, hypochlorous acid, nezvimwewo): KClO3+2HSO3NH2→2H2SO4+KCl+N2+H2O2 2HOCl+HSO3NH2→HSO3NCl2+2H2O |
