Dab tsi yog huv 99% diphenylmethane kua ua hauj lwm 101-81-5?
Diphenylmethane (CAS {101-81-5) yog cov txheej txheem albockarbon muaj ob lub pob zeb me me uas sib txuas, nrog cov mis nyuj consula. Nyob rau hauv chav tsev kub, nws tshwm sim li muaj cov xim tsis muaj lub ntsej muag lossis kua nrog lub txiv kab ntxwv daj ntseg aroma.
Lub diphenylmethane muaj lub ntsiab lus melting 22-25.3 degree, ib qho npau taws ntawm 264-265 degree ntawm 264-26 G / ML ntawm 25 degree. Nws yog insoluble hauv dej tab sis soluble heev hauv cov kuab tshuaj ethanol thiab ether. Nrog lub eeb taw tes ntawm 127-130 degree, kev tiv thaiv hluav taws xob kom zoo yog tsim nyog thaum lub sijhawm tuav.

Kev siv
Hauv kev ua haujlwm ntawm cov tshuaj zoo, diphenylmethane ua haujlwm raws li lub tsev loj heev rau cov qauv molecetylmether, qhov twg nws conjoulated molecular violet pab txhawb kom pom cov xim ua kom meej. Nws cov derivatives tseem ua haujlwm hauv cov fragrance formulations vim lawv floral lossis musky profiles, nrhiav cov ntawv thov, tshuaj pleev ib ce, thiab khoom noj tshuaj ntxiv.
Tsis pub dhau cov khoom lag luam science, diphenylmethane lub siab boiling point ua rau nws haum raws li kev kub siab hloov nruab nrab hauv cov txheej txheem, suav nrog cov txheej txheem yas thiab roj hmab vulcanization. Los ntawm phosgenation cov tshuaj tiv thaiv, nws hloov mus rau methylene diphylene diphylene diphenyanate (Mthorethane ua npuas ncauj rau kev tsim cov khoom siv polyurethane, pleev xim, thiab cov nplaum.
Cov Ntaub Ntawv Kev Nyab Xeeb
Toxicity thiab Kev Tiv Thaiv
Acute toxicity: oral LD₅₀ in rats is about 2250 mg/kg (may cause liver damage at high doses), and dermal LD₅₀ in rabbits>5000 mg / kg.
IRRITITE: Me taub voos rau cov tawv nqaij thiab qhov muag, nqus tau cov pa ntawm vapor siab yuav ua rau ua pa tsis xis nyob.
Kev tiv thaiv kev tiv thaiv: Cov hnab looj tes hnab looj tes tiv thaiv thiab goggles thaum ua haujlwm kom tsis txhob muaj kev sib cuag nrog oxidants.
Kev coj ib puag ncig
Cov neeg tsis muaj peev xwm: Nws tuaj yeem cuam tshuam los ntawm cov kab mob me hauv av thiab dej, tab sis qhov nrawm yog qeeb; Nws yog tsuas yog decomposed los ntawm photooxidation hauv cov huab cua, nrog ib nrab-lub neej ntawm 8-14 teev.
Kev phom sij ecological: nws yog tshuaj lom rau dej tsiaj muaj sia (xws li ntses), thiab tawm mus rau hauv cov dej ntuj yuav tsum zam.
