Ibintu bigira ingaruka kuri tetrahydrofuran no kubishyira mubikorwa
Tetrahydrofuran (THF) ni umusemburo ukoreshwa cyane mu nganda z’imiti ufite ubushobozi buke ndetse n’uburozi buke, bityo ukaba warakoreshejwe cyane mu bijyanye n’imiti, imiti n’ibikoresho bya siyansi. Muri iyi nyandiko, tuzaganira byimbitse ibiranga shingiro biranga tetrahydrofuran, ibintu bigira ingaruka nakamaro kayo mubikorwa bifatika.
I. Ibintu shingiro bya tetrahydrofuran ningingo yabyo
Tetrahydrofuran (THF) ni cyclic ether hamwe na formula ya chimique C4H8O. Nkibisanzwe bikoreshwa cyane, tetrahydrofuran ni amazi atagira ibara kandi abonerana mubushyuhe bwicyumba kandi afite ihindagurika ryinshi. Tetrahydrofuran ifite aho itetse igera kuri 66 ° C (hafi 339 K), bigatuma byoroha guhinduka no gukira mubikorwa byinshi bya shimi. Ingingo ya Tetrahydrofuran itetse nayo isobanura ko ishobora gukurwa muri sisitemu yo kubyitwaramo vuba, bikagabanya kwivanga hamwe nibisubizo byakurikiyeho.
Ibintu bigira ingaruka kuri tetrahydrofuran
Nubwo ingingo itetse ya tetrahydrofuran ifite agaciro gahamye mubuvanganzo bwa shimi, mubikorwa aho guteka kwa tetrahydrofuran bishobora guterwa nimpamvu nyinshi:
Ingaruka zumuvuduko wibidukikije: Ingingo itetse ya tetrahydrofuran iratandukanye nigitutu cyibidukikije. Ku muvuduko usanzwe w'ikirere, aho tetrahydrofuran itetse ni 66 ° C. Munsi yumuvuduko mwinshi cyangwa muto, ingingo itetse izahinduka. Mubisanzwe, umuvuduko mwinshi, niko hejuru ya tetrahydrofuran; muburyo bunyuranye, mu cyuho, ingingo yo guteka izagabanuka.

Ingaruka yubuziranenge: Umwanda muri tetrahydrofuran uzagira ingaruka kumwanya wacyo. Niba igisubizo cya tetrahydrofuran kirimo amazi menshi cyangwa andi mabi yanduye, aho itetse irashobora gutandukana naya tetrahydrofuran. By'umwihariko, kuba hari ubuhehere, bushobora gushonga gato mumazi, burashobora gukora azeotrope hamwe na THF, bikavamo impinduka nto mumwanya utetse.

Azeotropic phenomena: Mubikorwa, tetrahydrofuran ikunze kuvangwa nindi mashanyarazi kugirango ikore imvange ya azeotropique. Ingingo zitetse zivanze mubisanzwe ziratandukanye nibice bimwe kandi azeotropy igora inzira yo gutandukana. Kubwibyo, mugihe uhitamo tetrahydrofuran nkigisubizo, ni ngombwa gusobanukirwa imyitwarire ya azeotropique hamwe nibindi bikoresho.

III. Gushyira mubikorwa bya tetrahydrofuran kubira inganda
Ibintu bitetse bya tetrahydrofuran bifite akamaro gakomeye mugukora imiti:
Gusubirana no kongera gukoresha ibishishwa: Kubera ko tetrahydrofuran ifite aho itetse, biroroshye gukira bivuye mu ruvangitirane ruvanze no kubitandukanya cyangwa ubundi buryo bwo gutandukana. Uyu mutungo ntabwo ufasha kugabanya ibiciro byumusaruro gusa, ahubwo unagabanya ingaruka kubidukikije.

Porogaramu muri polymerisation: Mubisubizo bimwe na bimwe bya polymerisation, tetrahydrofuran ifite aho itetse igereranije, ituma igenzura neza ubushyuhe bwimikorere kandi ikemeza ko reaction igenda neza. Guhindagurika kwayo kurashobora kandi gukurwaho vuba nyuma yigitekerezo, bikarinda ingaruka mbi kubicuruzwa.

Gushyira mu bikorwa ibiyobyabwenge: Tetrahydrofuran ikoreshwa kenshi nk'umuti mugikorwa cyo guhuza ibiyobyabwenge, aho itekera iringaniye, ifasha kugenzura neza uko ibintu byifashe. Imiterere ya Tetrahydrofuran yihuta cyane ituma bigira ingaruka nziza muburyo bwo kwigunga no kwezwa.

Umwanzuro
Ingingo itetse ya tetrahydrofuran nimwe mubintu byingenzi mubikorwa byinganda. Gusobanukirwa aho tetrahydrofuran itetse hamwe ningaruka zabyo bishobora gufasha ibigo byimiti kugenzura neza uko ibintu byifashe mu musaruro nyirizina no kuzamura ubwiza n’umusaruro w’ibicuruzwa. Gukoresha mu buryo bushyize mu gaciro ibimenyetso biranga bishobora gufasha kugera ku gutunganya neza umutungo no guteza imbere ibidukikije. Iyo uhisemo kandi ukoresha tetrahydrofuran nkigisubizo, gusuzuma neza ibiranga aho bitetse nibintu bigira ingaruka nurufunguzo rwo kurinda umutekano no gukora neza mubikorwa bya shimi.
