Tetraydrofuran

Tetraydrofuran, amagambo asobanutse thf, ni uruvange rwamagana. Ni uw'ishuri rya ether, ni ibintu byimpumuro ya Furan ibicuruzwa byuzuye hydrogenation.

Tetraydrofuran nimwe muri aba bahanga muri polar ikomeye. Ikoreshwa nka polar yo hagati muburyo bwa shimi no gukuramo. Nibintu bitagira ibara bihindagurika mubushyuhe bwicyumba kandi bifite impumuro isa na ether. Gushonga mumazi, Ethanol, Ether, Acetone, imitinyabumbanyi benzene nibindi bisemukirana, bizwi nka "Solvel Solven". Mu cyumba cy'ubushyuhe n'amazi birashobora kuba bidashoboka igice, ubucuruzi bwaka butemewe ni ugukoresha iyi ngingo kuri Tetrahydrofuran Phige Amazi menshi. Kubera impengamiro ya thf kugirango ikore proxide mububiko, Antioxidant Bht isanzwe yongeweho ibicuruzwa byinganda. Ibirimo ubushuhe ≦ 0.2%. Ifite ibiranga uburozi buke, ahantu hatetse hasi hamwe namazi meza.

Imiti yimiti:Amazi atagira ibara, hamwe na ether. Ivanze n'amazi, inzoga, ketone, benzene, ester, ether, na hydrocarbone.

Porogaramu Nkuru:

1.. Ibikoresho fatizo bya synthesis synthesis:

Tetrahydrofuran ubwayo irashobora kuba polycondesation (nukuzana impeta ya catic repolymeylene) muri polytetramethylene ether diol (ptmeg), uzwi kandi nka tatraydrofuran homopolyl. PTMEG na Toluene Diisocyate (TDI) bikozwe mu kurwanya kurwanya, kurwanya peteroli, imikorere yubushyuhe buke, imbaraga nyinshi za reberi idasanzwe; Guhagarika polyether ibikoresho bya polstique byateguwe hamwe na Dimethyl Terephthalate na 1, 4-Butanediol. PTMEG hamwe nuburemere bwa molekile ya 2000 na p-methylene bis (4-phenyl) gukora filestic fibre ya polastike (MDI), reberi idasanzwe hamwe na reberi idasanzwe hamwe nintego yihariye yo guhora ibikoresho fatizo. Gukoresha cyane kwa thf ni kuba umusaruro wa PTMEG. Nk'uko imibare ikaze, hafi 80% yisi yose ikoreshwa mugukora PTMEG, na PTMEG ikoreshwa cyane cyane kumusaruro wa fibre ya spandex.

2. Umuti ufite imikorere myiza:

Tetrahydrofuran ni ikintu gikunze gukoreshwa cyane, cyane cyane kijyanye no gushonga chloride na Butyl aniline, antical aniline, hamwe na chicarroication muri electraplanta, hamwe na filime ya anticorrotsing ubunini bwa laser kandi bikaba byiza. Soliveni ya kaseti ya kaseti, PVC hejuru yubuso, isukura React, ikuraho Filime ya PVC, ipaki ya SELLOPHONE

3. Ikoreshwa nkibikoresho fatizo bya synthesis kama nka farumasi:

Kugirango umusaruro wa Tetrahydrothiophenephenephenephenephene, 1.4- Dichloroethane, 2.3- Dichlotrahyhydrofuran, Valerolactone, Butyl Lactone na Pyrrodone. Mu nganda za farumasi, zikoreshwa muri synthesis ya Coughbixin, RifiMyCin, Progesterone hamwe nibiyobyabwenge bimwe bya softmone. TetraydrorioTheriopheriopheriopheolopheol yakozwe na hydrogen sulfdide, ishobora gukoreshwa nkumukozi wa odor muri gaze ya lisansi (indangamuntu), kandi nacyo nicyo kintu nyamukuru cyimiti.

4. Ibindi bikoresho:

Chromatographic Solvent (Gel Permetation Chromatografiya), ikoreshwa muburyo busanzwe bwa gaze, gukuramo ibikoresho bya macetyle igihugu kiriyongera, kandi icyifuzo cya Tetraydrofuran cyerekana kandi iterambere ryihuse Inzira.

Akaga:Tetrahydrofuran ni uw'ibyiciro 3.1 Amazi yavumbuwe afite flash yo hasi, yaka cyane, imyuka irashobora gukora imvange iturika hamwe na 1.5% ~ 12% (agace k'ijwi), hamwe no kurakara. Kamere yayo yaka cyane nayo ni akaga. Umutekano munini uhangayikishijwe na Thfs ni ugukora buhoro buhoro buhoro buhoro peroxides mugihe cyahuriweho numwuka. Kugabanya iyi mbaraga, ubucuruzi buboneka mu bucuruzi akenshi bwuzuzwa hamwe na 2, 6-di-tert-Butylp-Cread (bht) kubuza umusaruro wa peroxide kama. Muri icyo gihe, thf ntigomba gukama kuko peroxide ogh kama izibanda mu gisimwe.

Gukoresha Gutunganya:imikorere ifunze, guhumeka byuzuye. Abakora bagomba gutozwa byumwihariko kandi bagagumaho neza uburyo bwo gukora. Birasabwa ko abakora bambara mask ya gazi (mask ya kimwe cya kabiri), ibirahuri birinda umutekano, imyenda yo kurwanya ihamye, na gants ya rubber. Irinde umuriro, isoko, nta itabi mu kazi. Koresha sisitemu yo guturika-ibikoresho bifatika. Irinde steam guhunga umwuka wakazi. Irinde guhura na Oxidants, acide na base. Igipimo cyuruzi kigomba kugenzurwa mugihe cyuzuye, kandi hagomba kubaho igikoresho gihagaze kugirango wirinde kwegeranya electrostatic. Mugihe ukemura, urumuri no gupakurura bigomba gukorwa kugirango wirinde ibyangiritse kubipfunyika nibikoresho. Ifite ibikoresho bitandukanye nuburyo buhuye nibikoresho byumuriro nibikoresho byo kuvura byihutirwa. Ikintu cyubusa gishobora kuba kirimo ibisigisigi byangiza.

Ingamba zo kubika:Mubisanzwe ibicuruzwa bifite inhibitor. Kubika mu bubiko bukonje, buhumeka. Irinde umuriro n'ubushyuhe. Ubushyuhe bwububiko ntibugomba kurenga 30 ℃. Ipaki igomba gushyirwaho kashe kandi idahuye numwuka. Igomba kubikwa ukundi kuva kuri okiside, acide nibishingiro, kandi ntibigomba kuvanga. Guturika-Ibimenyetso byo gucana hamwe nibikoresho bifatika byafashwe. Ntukoreshe ibikoresho bya mashini nibikoresho bikunze kurabarika. Agace k'ububiko kagomba kuba gifite ibikoresho byo kuvura byihutirwa ndetse n'ibikoresho bikwiye.
