Ntoo yog qhov ua rau muaj kab thiab fungi uas tshwm sim vim cov dej noo hauv nws. Khaws kom qhuav yog qhov kev tiv thaiv zoo tshaj plaws. Organic antiseptics yog siv los impregnate tsis nyob hauv thaj chaw. Ib tug ntawm lawv yog anthracene roj, uas muaj ib tug xov tooj ntawm lwm yam khoom.
Kev piav qhia
Anthracene roj yog cov khoom lag luam ntawm cov thee tar, nws cov xim yog ntsuab daj. Qhov kub ntawm cov khoom yog nyob rau hauv qhov kub ntawm 280-360 ° C. Hauv cov ntsiab lus feem pua, cov muaj pes tsawg leeg suav nrog anthracene (5%), phenanthrene (20%) thiab carbazole (6%), tus so yog tsim los ntawm lwm cov tshuaj tsw qab. Nws muaj qhov ntse thiab tsis hnov tsw tsw ntxhiab vim phenol thiab sulfur compounds. Ua haujlwm nrog nws, cov kws tshaj lij tau hnav looj tsom iav thiab zuag qhia tag nrho.
Kev tsis saib xyuas thaum ua haujlwm yog fraught nrog o ntawm daim tawv muag, khaus ntawm cov mucous, hlawv thiab khaus ntawm daim tawv nqaij. Ua rau hlawv ntawm daim tawv nqaij ncaj qha. Cov cheeb tsam ntawm daim tawv nqaij uas tsis muaj kev tiv thaiv los ntawm cov khaub ncaws tshwj xeeb yog smeared nrog cov khoom ntom ntom: glycerin, starch los yog gelatin.
Anthraceneroj muaj cov yam ntxwv kub hauv qab no:
- flash point - 141 °C;
- flash point - 171 °C;
- tus kheej qhov kub hnyiab - 548 ° C;
- vapor flammability txwv - 120 ° C thiab 160 ° C.
Tom qab txias cov khoom, cov khoom muag muag tawm, uas feem ntau muaj anthracene.
Tau txais roj
Anthracene roj yog tau los ntawm coking cov resin, uas yog tsim nyob rau hauv ib tug zoo xws li cov txheej txheem nrog thee, coke thiab roj. Txias cov feem no muab cov anthracene crude nyob rau hauv lub xeev crystalline. Tom qab nws pom, cov kua theem tseem nyob, uas yog cov roj anthracene. Hauv cov nroj tsuag carbon dub, nws yog hu ua thee roj thiab siv los tsim cov kua qaub. Rau tib lub hom phiaj, nws feem thib ob kuj tau siv.
Anthracene Oil Applications
Fluorene, phenanthrene, fluoranthene thiab indole yog tau los ntawm cov lus piav qhia. Ua li no, cov khoom ua kua yog raug rau qhov kub thiab txias, tom qab lim tawm cov precipitate, 15% muaj cov anthracene. Tom ntej no, ntxuav yog nqa tawm nrog cov kuab tshuaj uas anthracene tsis zoo soluble. Qhov no tawm hauv qhov sib tov uas muaj 20% carbazole. Nws hloov mus rau sulfate siv cov tshuaj benzene.
Thaum nws los txog rau kev tsim cov kua qaub, cov roj anthracene lossis nws cov feem yuav tsum ua tau raws li ob qhov kev xav tau: muaj tsawg dua 1.5% noo noo thiab muaj qhov distillation txog 360 ntau dua 65%. Cov tshuaj tua kab mob organic no tau siv dav kom tau txais cov kua qaub.
rauimpregnation ntawm ntoo thiab carbon dub anthracene roj yog npaj los ntawm ib tug tshwj xeeb txoj kev. Nws yog ib qho tsim nyog yuav tsum tau cais cov crude anthracene los ntawm cov feem, uas ua rau yuav tsum muaj cov cuab yeej tshwj xeeb. Lub concentration ntawm cov khoom crystalline yog tsawg, uas ua rau nws muaj peev xwm siv apparatus nrog stirrers rau cov hom phiaj no. Lawv feem ntau yog kab rov tav tso tsheb hlau luam nrog cov paddles sib quas ntus. Lawv qhov txias txias tshwm sim los ntawm cov dej ntws ntawm sab nrauv. Ntawm 70-80 ° C, cov khoom siv anthracene yog muab, feem ntau absorbing roj yog nkag nrog nws. Cov txheej txheem txuas ntxiv mus txog thaum cov crystals poob tawm. Qhov nyuaj yog nyob rau hauv lub siab viscosity, uas ua rau nws nyuaj rau diffuse qhov muaj pes tsawg leeg.
Kev xav tau roj anthracene kuj tuaj yeem pom hauv tshuaj. Roj derivatives yog siv nyob rau hauv ntau yam tshuaj. Pharmacotherapeutic kev txiav txim nyob ntawm cov qauv tshuaj. Anthracene derivatives render:
- Regenerating and stimulating action.
- Laxative action.
- YDiuretic thiab nephrological action.
- Tsim cov nyhuv choleretic.
- Muaj tshuaj tiv thaiv kab mob thiab tshuaj tua kab mob.
Zoo kawg
Kev npaj raws li cov roj anthracene yog tshuaj tua kab, fungicidal thiab bactericidal. Impregnation ntawm ntoo nrog xws li ib tug muaj pes tsawg leeg tiv thaiv kev loj hlob ntawm dub txiv hmab txiv ntoo thiab lichen cancer. Nws yog ib qho zoo tshaj plaws rau kev tsim khoom loj vim nws ntau yam kev siv.
