N,N-Dimethylformamide CAS 68-12-2
I-Dimethylformamide iwuketshezi olungenambala futhi olusobala. Akuyona nje into esetshenziswa kakhulu yamakhemikhali eluhlaza, kodwa futhi iyi-solvent enhle kakhulu enezinhlobonhlobo zokusetshenziswa. I-Dimethylformamide iyimpahla eluhlaza ebalulekile yezimboni zemithi, i-petrochemical, isikhumba nezinye.
I-Dimethylformamide ibizwa ngokuthi i-DMF. Kuyinhlanganisela lapho iqembu le-hydroxyl le-formic acid lithathelwa indawo yiqembu le-dimethylamino, ne-molecular formula HCON(CH3)2. Iwuketshezi lwamaphuzu aphezulu abilayo angenambala futhi olusobala olunephunga elilula le-amine kanye nokuminyana okuhlobene okungu-0.9445 (25℃). Iphuzu lokuncibilika -61℃. Iphoyinti lokubilisa 152.8 ℃. Iphoyinti le-Flash 57.78℃. Ukuminyana komhwamuko 2.51. Umfutho we-vapor 0.49kpa (3.7mmHg25℃). Iphoyinti le-Autoignition lingu-445 ℃. Umkhawulo wokuqhuma kwengxube yesitimu nomoya ngu-2.2 ~ 15.2%. Ukuchayeka emalangabini avulekile nokushisa okuphezulu kungase kubangele ukusha nokuqhuma. Ingasabela ngobudlova nge-sulfuric acid egxilile kanye ne-nitric acid evuthayo futhi iphinde iqhume. Ixubene namanzi nezinyibilikisi eziningi eziphilayo I-Chemicalbook. Kuyi-solvent evamile yokusabela kwamakhemikhali. I-dimethylformamide ehlanzekile ayinalo iphunga, kodwa izinga lezimboni noma i-dimethylformamide ewohlokayo inephunga lezinhlanzi ngoba iqukethe ukungcola kwe-dimethylamine. Igama livela eqinisweni lokuthi liyi-dimethyl esikhundleni se-formamide (i-amide ye-formic acid), futhi womabili amaqembu e-methyl atholakala ku-athomu ye-N (nitrogen). I-Dimethylformamide iyi-polar (hydrophilic) aprotic solvent enephuzu eliphezulu lokubilisa, elingase likhuthaze indlela yokusabela ye-SN2. I-Dimethylformamide yenziwe nge-formic acid ne-dimethylamine. I-Dimethylformamide ayizinzile (ikakhulukazi emazingeni okushisa aphezulu) lapho kukhona izisekelo eziqinile njenge-sodium hydroxide noma ama-acids aqinile njenge-hydrochloric acid noma i-sulfuric acid, futhi i-hydrolyzes ibe i-formic acid ne-dimethylamine.
Azinzile emoyeni futhi lapho ishiselwa kuze kube ukubila. Uma izinga lokushisa lingaphezu kuka-350°C, lilahlekelwa amanzi futhi likhiqize i-carbon monoxide ne-dimethylamine. I-N,N-dimethylformamide iyi-aprotic polar solvent enhle kakhulu engancibilikisa izinto eziningi eziphilayo nezingaphili futhi ixubana namanzi, utshwala, ama-aldehyde, ama-ketone, ama-esters, ama-halogenated hydrocarbon nama-hydrocarbon anephunga elimnandi. . Ukuphela kwe-molecule ye-N,N-dimethylformamide enecala elihle lizungezwe amaqembu e-methyl, akha umgoqo we-Chemicalbook wendawo ovimbela ama-ion angalungile ukuthi angasondeli futhi ahlobanise ama-ion amahle kuphela. Ama-anion angenalutho asebenza kakhulu kune-anion exazululiwe. Ukusabela kwe-ionic okuningi kulula ukukwenza ku-N,N-dimethylformamide kunezincibilikisi ezivamile ze-protic. Isibonelo, ama-carboxylate nama-halogenated hydrocarbons asabela ku-N,N-dimethylformamide ekamelweni lokushisa. , ingakhiqiza ama-ester anesivuno esikhulu, futhi ifaneleka ngokukhethekile ukuhlanganiswa kwama-ester avinjwe ngokuqinile.

I-Ethylenediaminetetraacetic acid CAS: 60-00-4
izakhiwo zamakhemikhali
Lo mkhiqizo ucwebezela emanzini njengempushana emhlophe. Ukuncibilika emanzini ku-25℃ ngu-0.5g/L. Ayincibiliki emanzini abandayo, utshwala nezincibilikisi ezijwayelekile zemvelo. Incibilika ku-sodium hydroxide, i-sodium carbonate nezixazululo ze-ammonia.
Indlela yokukhiqiza:
Ukusabela kwe-ethylenediamine ne-chloroacetic acid. Faka u-100kg we-chloroacetic acid, u-100kg weqhwa kanye no-135kg wesixazululo se-sodium hydroxide (30%) eketelani lokusabela, bese wengeza u-18kg wama-83% kuya ku-84% we-ethylenediamine ngaphansi kokunyakaziswa. Fudumeza ku-15°C ihora elingu-1. Engeza i-30Chemicalbook% isisombululo se-sodium hydroxide ngamaqoqo angu-10L isikhathi ngasinye. Ngemva kokuhlanganisa ngakunye, engeza enye inqwaba ngemva kokuba isisombululo sokuhlola i-phenolphthalein singabonisi okubomvu. Gcina ekamelweni lokushisa 12h. Shisisa ufike ku-90°C futhi ushintshe umbala ngekhabhoni ecushiwe. Hlunga, geza insalela yokuhlunga ngamanzi, futhi ekugcineni ulungise inani le-pH libe ngu-3 nge-concentrated hydrochloric acid. Pholisa futhi ucwebezele, hlunga futhi ugeze ngamanzi kuze kube yilapho kungabikho ukusabela kwe-chloride ion. Imikhiqizo eyomisiwe.
Ukusabela kwe-ethylenediamine nge-formaldehyde ne-sodium cyanide. Xuba u-60% we-ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution ne-sodium hydroxide, bese ugcine ingxube ku-20°C isikhathi esingu-0.5h. Bese wengeza i-formaldehyde aqueous solution dropwise. Ngemva kokusabela, i-chemicalbook yachithwa futhi amanzi ahwamuka. Bese uphinda umsebenzi ongenhla, wengeza i-formaldehyde eyeqile okokugcina ukuze i-sodium cyanide isabele ngokuphelele. Lungisa i-pH ibe ngu-1.2 nge-asidi exubile. Imvula emhlophe iyana, iyahlungwa, igezwe ngamanzi, bese yomiswa ku-110°C. Thola umkhiqizo.
