Igishushanyo kizwi cyane kuri chimique reagent pH Icyerekana 99% Thymolphthalein CAS 125-20-2
Iterambere ryacu rishingiye kubikoresho byateye imbere, impano nziza kandi dukomeza gushimangira imbaraga zikoranabuhanga mugushushanya gukundwa na Chemical Reagent pH Icyerekezo 99%Thymolphthalein CAS 125-20-2, Reka dufatanye mu ntoki kugirango dufatanye kubyara ejo hazaza heza. Turakwishimiye cyane gusura ikigo cyacu cyangwa ukaduhamagarira ubufatanye!
Iterambere ryacu riterwa nibikoresho bigezweho, impano nziza kandi dukomeza imbaraga zikoranabuhanga kuriThymolphthalein na 125-20-2Ibicuruzwa byacu byoherejwe cyane cyane mu majyepfo y’iburasirazuba bwa Aziya Euro-Amerika, no kugurisha mu gihugu cyacu cyose. Kandi ukurikije ubwiza buhebuje, igiciro cyiza, serivisi nziza, twabonye ibitekerezo byiza kubakiriya mumahanga. Urahawe ikaze kwifatanya natwe kubishoboka byinshi ninyungu. Twishimiye abakiriya, amashyirahamwe yubucuruzi ninshuti ziturutse impande zose zisi kutwandikira no gushaka ubufatanye kubwinyungu rusange.
Thymolphthalein'izina rya siyansi ni "3,3-bis (4-hydroxy-5-isopropyl-2-methylphenyl) -phthalide", ni reagent kama. Imiti yimiti ni C28H30O4, naho uburemere bwa molekile ni 430.54. Nifu ya kirisiti yera. Irashobora gushonga byoroshye muri ether, acetone, acide sulfurike nigisubizo cya alkaline, kandi ntigishonga mumazi. Bikunze gukoreshwa nkibipimo bya aside-shingiro, kandi pH ihinduka ryamabara ni 9.4-10.6, naho ibara rihinduka kuva ibara ritagira ibara ryubururu. Iyo ikoreshejwe, akenshi itegurwa mumuti wa 0.1% 90%. Irategurwa kandi nibindi bipimo kugirango ikore ibipimo byoroheje bihujwe kugirango ibara ryayo rihindurwe kandi bigaragare neza.

Thymolphthaleinikoreshwa kenshi nka aside-ishingiro ryerekana, hamwe na pH ihindura ibara rya 9.4 kugeza 10.6, naho ibara rihinduka kuva ibara ritagira ibara ry'ubururu. Iyo ikoreshejwe, akenshi itegurwa nkigisubizo cya 0.1% 90% ya Ethanol, kandi akenshi ivangwa nibindi bipimo kugirango ikore ibipimo bivanze kugirango ibara ryayo rihindurwe kandi bigaragare neza kubireba. Kurugero, igipimo cyakozwe mukuvanga 0.1% yumuti wa Ethanol wiyi reagent hamwe na 0.1% ya Ethanol yumuti wa fenolphthalein ntigira ibara mumuti wa acide, umutuku mubisubizo bya alkaline, hanyuma ukazamuka kuri pH 9.9 (guhindura ibara), byoroshye kubibona.
