makemikari zvinhu
Ichi chigadzirwa chinopenya kubva mumvura sehupfu chena. Kunyungudika mumvura pa25 ℃ ndiyo 0.5g/L. Insoluble mumvura inotonhora, doro uye general organic solvents. Soluble mu sodium hydroxide, sodium carbonate uye ammonia mhinduro.
Nzira yekugadzira:
Reaction ye ethylenediamine uye chloroacetic acid. Wedzera 100kg yechloroacetic acid, 100kg yeaizi uye 135kg yesodium hydroxide solution (30%) mugetero rekuita, wobva wawedzera 18kg ye83% kusvika 84% ethylenediamine pasi pekudzvinyirirwa. Isa pa 15°C kweawa imwe. Wedzera 30Chemicalbook% sodium hydroxide solution mumabhechi e10L nguva yega yega. Mushure mekuwedzera kwega kwega, wedzera imwe batch mushure mekunge phenolphthalein test solution isingaratidzi mutsvuku. Chengetedza mukamuri tembiricha kwe12h. Kupisa kusvika 90°C uye decolorize ne activated carbon. Sefa, geza sefa nemvura, uye pakupedzisira gadzirisa pH kukosha kune 3 ine concentrated hydrochloric acid. Kutonhorera uye kupenya, sefa uye geza nemvura kusvika pasina chloride ion reaction. Zvigadzirwa zvakakanyiwa.
Reaction ye ethylenediamine ine formaldehyde uye sodium cyanide. Sanganisa 60% ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution uye sodium hydroxide, uye chengetedza musanganiswa pa 20 ° C kwe 0.5h. Wobva wawedzera formaldehyde aqueous solution dropwise. Mushure mekuita, iyo chemicalbook yakaderedzwa uye mvura yakanyungudutswa. Wobva wadzokorora oparesheni iri pamusoro, uchiwedzera yakawandisa formaldehyde kekupedzisira kubvumira iyo sodium cyanide kuita zvachose. Gadzirisa pH kusvika 1.2 ine dilute acid. Mvura yakachena inonaya, yakasefa, yakagezwa nemvura, uye yakaomeswa pa110°C. Tora chigadzirwa.
Nzvimbo yekushandisa
Ethylenediaminetetraacetic acid (EDTA) chinhu chakakosha chekugadzirisa. EDTA inoshandiswa zvakanyanya uye inogona kushandiswa se bleaching fixative mukugadzirisa kwemavara photosensitive zvinhu, dyeing anobatsira, faibha process anobatsira, cosmetic additives, ropa anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiators, EDTA ichelate Inomiririra zvinhu zvemusanganiswa. Inogona kuumba yakagadzika mvura-inonyungudika makemikari complexes ane alkali simbi, zvisingawanzo pasi zvinhu uye shanduko simbi. Kuwedzera kune sodium munyu, kunewo ammonium munyu uye akasiyana munyu akadai iron, magnesium, calcium, mhangura, manganese, zingi, cobalt, uye aruminiyamu. Imwe neimwe yemunyu iyi ine mashandisirwo akasiyana. Pamusoro pezvo, EDTA inogona zvakare kushandiswa kukurumidza kuburitsa simbi dzinokuvadza kubva mumuviri wemunhu uye kuita basa rekubvisa. Iyo zvakare mushonga wekuchenesa mvura. EDTA zvakare chiratidzo chakakosha, asi chinoshandiswa titrate simbi nickel, mhangura, etc. Kana inoshandiswa, inofanira kushandiswa pamwe chete neammonia kuti iite sechiratidzo.
