Toluene yog reactive ntau dua li benzene rau electrophilic reagents vim muaj cov methyl pawg txuas nrog lub nplhaib benzene. Cov pab pawg methyl yog ib qho hluav taws xob- pab pawg pub dawb, uas ua rau kom cov electron ceev ntawm lub nplhaib benzene los ntawm ob qho tib si inductive thiab hyperconjugative.
Vim li cas benzene thiaj li tsis muaj kev ruaj ntseg?
Nws yog qhov ua tiav tag nrho ntawm kev sib koom ua ke orbitals, lossis lub plhaub kaw, uas muab lub nplhaib benzene nws cov thermodynamic thiab tshuaj lom neeg ruaj khov, ib yam li lub plhaub puv valence octet confers stability ntawm lub inert gases.
Vim li cas thiaj xaiv Gneebio?
Gneebio, nrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom, thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav. Tau ntau xyoo, peb tau cog lus rau kev lag luam tshuaj lom neeg ntawm cov khoom nruab nrab, cov khoom siv yas, cov tshuaj kho dej thiab cov tshuaj fungicides, thiab cov tshuaj niaj hnub.
Qhov zoo
1) Cov khoom xa tuaj me me thiab sub- ntim khoom muaj.
2). Muab COA, MSDS, Daim Ntawv Pov Thawj Kev Noj Qab Haus Huv, thiab Daim Ntawv Pov Thawj Keeb Kwm.
3) Zoo ua ntej, kev pabcuam zoo tshaj plaws.
