Kev siv
Nyob rau hauv cov tshuaj zoo nkauj, diphenylmethans ua haujlwm nruab nrab rau tripherylmethane ua rau muaj cov qauv siv crystal, qhov twg nws cov qauv kev sib cav sib ceg kom pom cov xim ua kom pom xim. 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.
Nyob rau hauv cov ntaub ntawv science, diphenylmethane hloov mus rau methylene diphylene diphylene dipenation cov khoom siv rau kev tsim cov khoom siv polyurethane ua npuas, ua npuas dej, thiab cov nplaum. Nws lub siab npau npau ua rau nws haum raws li kev kub siab hloov hloov hluav taws xob hauv nruab nrab hauv kev siv cov roj hmab thiab roj hmab volcanization.
Cov Ntaub Ntawv Kev Nyab Xeeb
Diphenylmethane muaj qhov ncauj tsis muaj txiaj ntsig (cov kab ncauj LD₅₀ yog li 2250 mg / kg), tab sis nws nqus tau cov pa hluav taws xob siab yuav ua pa tsis xis nyob. Nws tuaj yeem degraded los ntawm cov kab mob me hauv ib puag ncig, tab sis qhov ceev yog qeeb, thiab tawm mus tshem dej rau hauv lub cev dej yuav tsum tau zam.
