hunhu hwemakemikari
Chigadzirwa ichi chinobuda mumvura kuita upfu huchena. Kunyungudika mumvura pa25℃ i0.5g/L. Hachinyungudike mumvura inotonhora, doro uye zvinonyungudutsa zvakasikwa. Chinonyungudika mu sodium hydroxide, sodium carbonate uye ammonia solutions.
Nzira yekugadzira:
Kuita kwe ethylenediamine ne chloroacetic acid. Wedzera 100kg ye chloroacetic acid, 100kg yechando uye 135kg ye sodium hydroxide solution (30%) mu reaction kettle, wobva wawedzera 18kg ye 83% kusvika 84% ethylenediamine uchikurunga. Isa pa15°C kweawa imwe. Wedzera 30Chemicalbook% sodium hydroxide solution mumabhechi e10L nguva imwe neimwe. Mushure mekuwedzera kwega kwega, wedzera imwe batch mushure mekunge phenolphthalein test solution yasaratidza kutsvuka. Chengeta patembiricha yemukamuri kwemaawa gumi nemaviri. Pisa kusvika 90°C wobvisa ruvara ne activated carbon. Sefa, geza firita residue nemvura, uye pakupedzisira gadzirisa pH value kusvika 3 ne concentrated hydrochloric acid. Tonhodza woita crystallize, sefa wogeza nemvura kusvika pasina chloride ion reaction. Zvigadzirwa zvakaomeswa.
Kuita kwe ethylenediamine ne formaldehyde uye sodium cyanide. Sanganisa 60% ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution uye sodium hydroxide, wochengeta musanganiswa pa20°C kwemaawa 0.5. Wobva wawedzera formaldehyde aqueous solution. Mushure mekuita, bhuku remakemikari rakabviswa simba uye mvura yakapwanyika. Wobva wadzokorora zvataurwa pamusoro apa, wowedzera formaldehyde yakawandisa kekupedzisira kuti sodium cyanide iite zvese. Gadzirisa pH kusvika pa1.2 ne dilute acid. White precipitate yakapwanyika, yakasefetwa, yakagezwa nemvura, uye yakaomeswa pa110°C. Tora chigadzirwa.
Munda wekushandisa
Ethylenediaminetetraacetic acid (EDTA) chinhu chakakosha pakugadzirisa zvinhu. EDTA inoshandiswa zvakanyanya uye inogona kushandiswa se bleaching fixative mukugadzirisa zvinhu zvinonzwa ruvara, dyeing auxiliaries, fiber processing auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rabber polymerization initiators, EDTA chinhu chinomiririra zvinhu zvemusanganiswa. Inogona kugadzira stable water-soluble chemical complexes ne alkali metals, rare earth elements ne transition metals. Kuwedzera kune sodium salts, kunewo ammonium salts nemarudzi akasiyana-siyana emunyu akadai se iron, magnesium, calcium, copper, manganese, zinc, cobalt, uye aluminium. Imwe neimwe yemunyu iyi ine mashandisirwo akasiyana. Pamusoro pezvo, EDTA inogona zvakare kushandiswa kubvisa nekukurumidza radioactive metals dzinokuvadza kubva mumuviri wemunhu uye kuita basa rekubvisa chepfu. Iyo zvakare mushonga wemvura. EDTA chiratidzo chakakosha, asi inoshandiswa ku titrate metal nickel, copper, nezvimwewo. Kana ikashandiswa, inofanira kushandiswa pamwe chete neammonia kuti ishande sechiratidzo.
