Ikhemikhali yaselabhorethri enobuthi kakhulu - i-propargyl alcohol

Incazelo emfushane:

I-Propargyl Utshwala, ifomula yamangqamuzana C3H4O, isisindo samangqamuzana 56. Uketshezi olungenambala olusobala, oluguquguqukayo olunephunga elimnandi, olunobuthi, ukucasuka okukhulu esikhumbeni nasemasweni.I-intermediate in organic synthesis.Ikakhulu esetshenziselwa ukuhlanganiswa kwezidakamizwa ezilwa namagciwane kanye ne-anti-inflammatory sulfadiazine;Ngemuva kwe-hydrogenation eyingxenye, i-propylene alcohol ingakhiqiza i-resin, futhi ngemva kwe-hydrogenation ephelele, i-n-propanol ingasetshenziswa njengempahla eluhlaza ye-anti-tuberculosis drug ethambutol, kanye neminye imikhiqizo yamakhemikhali nemithi.Ingakwazi ukuvimbela i-asidi ku-iron, ithusi ne-nickel nezinye izinsimbi, ezisetshenziswa njengesikhiphi sokugqwala.Kusetshenziswa kakhulu ekukhishweni kukawoyela.Ingasetshenziswa futhi njenge-solvent, i-stabilizer yama-hydrocarbon e-chlorinated, i-herbicide kanye nesibulala-zinambuzane.Ingasetshenziselwa ukukhiqizwa kwe-acrylic acid, i-acrolein, i-2-aminopyrimidine, i-γ-picauline, i-vitamin A, i-stabilizer, i-corrosion inhibitor nokunye.

Amanye amagama: i-propargyl alcohol, i-2-propargyl - i-1-alcohol, i-2-propargyl alcohol, i-propargyl alcohol acetylene methanol.

Isingeniso

Idatha ye-Toxicological
Ubuthi obunamandla: ngomlomo LD50:70mg/kg kumagundane;
I-Rabbit percutaneous LD50: 16mg/kg;
Amagundane ahogele i-LD50:2000mg/m3/2h.

Idatha yemvelo
Kunobuthi ezintweni eziphila emanzini.Kungabangela imiphumela emibi endaweni yamanzi.
Inobuthi.Ukucasuka okukhulu kwesikhumba namehlo.

Izakhiwo Nozinzo
Gwema ukushisa.Gwema ukuthintana ne-oxidant eqinile, i-asidi eqinile, isisekelo esiqinile, i-acyl chloride, i-anhydride.
Inobuthi.Ingacasula kakhulu isikhumba namehlo.Kunconywa ukugqoka izibuko zokuzivikela kanye namagilavu ngesikhathi sokusebenza.

Indlela yokugcina

Gcina endaweni epholile, engenisa umoya.Gcina kude nomlilo nomthombo wokushisa.Izinga lokushisa akufanele lidlule ku-30 ℃.Gcina isiqukathi singangeni ndawo.Kufanele igcinwe ngokuhlukana nama-oxidants, ama-asidi, ama-alkali namakhemikhali adliwayo, futhi akufanele ihlanganiswe.Ungagcini ngobuningi noma isikhathi eside.Kwamukelwe izindawo zokukhanyisa ezingaqhumi futhi zokungenisa umoya.Ungayisebenzisi imishini namathuluzi ajwayele ukuba nenhlansi.Indawo yokugcina izofakelwe okokusebenza okuphuthumayo okuvuzayo kanye nezinto zokubamba ezifanele.Uhlelo lokuphatha "okuphindwe kabili" lwezinto ezinobuthi ngokweqile kufanele lusetshenziswe ngokuqinile.

Ngenxa yokuthi i-proPARgyl alcohol ine-flash point ephansi futhi ingasabela ngokuqinile lapho kukhona ukungcola, ukunakwa okukhethekile kufanele kukhokhwe ekuphepheni.Isitoreji kanye nezinto zokuhamba zesikhashana, ezitholakala ezitsheni zensimbi ezingenazo ukugqwala.Ukugcina isikhathi eside, iziqukathi ezifakwe insimbi engagqwali, ingilazi noma i-phenolic resin kufanele zisetshenziswe, futhi izinto ezifana ne-aluminium kufanele zigwenywe.Gcina futhi uthuthwe ngokwemithethonqubo yamakhemikhali avuthayo.

Sebenzisa

Isetshenziswa njenge-rust remover, chemical intermediate, corrosion inhibitor, solvent, stabilizer, njll. I-Stabilizer ye-organic synthesis of intermediates, solvents kanye nama-hydrocarbons ane-chlorine.

Ingasetshenziswa njenge-hydrochloric acid nezinye i-industrial pickling corrosion inhibitor ekwenzeni inqubo ye-acidizing fracturing kawoyela negesi Wells.Ingasetshenziswa njenge-corrosion inhibitor iyodwa, kungcono ukuba nomphumela we-synergistic nempahla, ukuze uthole ukusebenza kahle kokuvimbela ukugqwala okuphezulu.Isibonelo, ukuze kwandiswe ukuvimbela ukugqwala kwe-alkynyl alcohol kusixazululo se-sulfuric acid, i-sodium chloride, i-potassium chloride, i-calcium chloride, i-potassium bromide, i-potassium iodide noma i-zinc chloride nokunye ukusetshenziswa okuyinkimbinkimbi.

Okwedlule: Ukusetshenziswa kwe-butanediol ku-cosmetics

Olandelayo: I-Propargyl izokwenziwa i-polymerize futhi iqhume
