Zatsopano Zatsopano Thymolphthalein CAS 125-20-2 pa Zizindikiro za Acid-Base
Zida zoyendetsedwa bwino, gulu laluso lazogulitsa, ndi makampani otsogola pambuyo pogulitsa; Ndifenso m'mabanja akuluakulu ogwirizana, aliyense amene amatsatira gulu amapindula "kugwirizanitsa, kudzipereka, kulolerana" kwa Hot New Products.ThymolphthaleinCAS 125-20-2 ya Zizindikiro za Acid-Base, Kuti tiwonjezere kwambiri ntchito yathu, bungwe lathu limatumiza zida zambiri zakunja kwakunja. Takulandilani makasitomala ochokera kunyumba ndi kutsidya lina kuti mulumikizane ndi kufunsa!
Zida zoyendetsedwa bwino, gulu laluso lazogulitsa, ndi makampani otsogola pambuyo pogulitsa; Ndifenso m'mabanja akuluakulu ogwirizana, aliyense mwamtheradi amamamatira ku bungwe kuti apindule "kugwirizanitsa, kudzipereka, kulolerana" chifukwa , Pophatikiza kupanga ndi magawo amalonda akunja, titha kupereka mayankho okwana makasitomala potsimikizira kutumiza zinthu zoyenera pamalo oyenera panthawi yoyenera, zomwe zimathandizidwa ndi zambiri zomwe takumana nazo, kuthekera kopanga kwamphamvu, mtundu wosasinthika, kusiyanasiyana kwazinthu zogulitsa komanso kuwongolera malonda athu pambuyo pa malonda athu. Tikufuna kugawana malingaliro athu ndi inu ndikulandila ndemanga ndi mafunso anu.
ThymolphthaleinDzina la sayansi ndi “3,3-bis(4-hydroxy-5-isopropyl-2-methylphenyl)-phthalide”, yomwe ndi organic reagent. Njira yamankhwala ndi C28H30O4, ndipo kulemera kwa maselo ndi 430.54. Ndi ufa wa crystalline woyera. Amasungunuka mosavuta mu ether, acetone, sulfuric acid ndi alkaline solutions, komanso osasungunuka m'madzi. Nthawi zambiri amagwiritsidwa ntchito ngati chizindikiro cha acid-base, ndipo kusintha kwa mtundu wa pH ndi 9.4-10.6, ndipo mtundu umasintha kuchoka ku mtundu wopanda utoto kupita ku buluu. Akagwiritsidwa ntchito, nthawi zambiri amakonzedwa kukhala 0.1% 90% ethanol solution. Amakonzedwanso nthawi zambiri ndi zizindikiro zina kuti apange chizindikiro chophatikizika chofatsa kuti chipangitse kusintha kwake kwamtundu kukhala kocheperako komanso kuwonetsetsa bwino.
| ITEM | ZOYENERA | ZOtsatira |
| Chizindikiritso | Ufa woyera mpaka woyera | Zimagwirizana |
| 1H-NMR | Chiwonetsero chofanana ndi cholozera | Pitani |
| HPLC chiyero | ≥98% | 99.6% |
| Kutaya pakuyanika | 1% kuchuluka | 0.24% |
Thymolphthalein nthawi zambiri amagwiritsidwa ntchito ngati chizindikiro cha acid-base, chokhala ndi pH mtundu wa kusintha kwa 9.4 mpaka 10.6, ndi kusintha kwa mtundu kuchokera ku mtundu wopanda mtundu kupita ku buluu. Akagwiritsidwa ntchito, nthawi zambiri amakonzedwa ngati njira ya 0,1% 90% ya ethanol, ndipo nthawi zambiri amasakanizidwa ndi zizindikiro zina kuti apange chizindikiro chosakanikirana kuti mtundu wake usinthe mtundu ukhale wocheperako komanso womveka bwino kuti uwone. Mwachitsanzo, chizindikiro chopangidwa ndi kusakaniza 0,1% Mowa njira ya reagent ndi 0,1% Mowa njira ya phenolphthalein ndi colorless mu njira acidic, wofiirira mu njira zamchere, ndipo ananyamuka pa pH 9.9 (mtundu kusintha mfundo), amene n'zosavuta kuona.
Zogulitsa zimayikidwa m'thumba, 25kg / ng'oma
Zida zoyendetsedwa bwino, gulu laluso lazogulitsa, ndi makampani otsogola pambuyo pogulitsa; Ndifenso m'mabanja akuluakulu ogwirizana, aliyense mwamtheradi amapindula ndi "kugwirizana, kudzipereka, kulolerana" kwa Hot New Products Thymolphthalein CAS 125-20-2 for Acid-Base Indicators, Kuti tiwonjezere kwambiri ntchito yathu, bungwe lathu limatumiza zida zambiri zakunja zakunja. Takulandilani makasitomala ochokera kunyumba ndi kutsidya lina kuti mulumikizane ndi kufunsa!
Hot New Products Thymolphthalein ndi CAS 125-20-2, Pophatikiza kupanga ndi magawo azamalonda akunja, titha kupereka mayankho okwana makasitomala potsimikizira kutumizidwa kwa zinthu zoyenera pamalo oyenera panthawi yoyenera, zomwe zimathandizidwa ndi zomwe takumana nazo, kuthekera kopanga kwamphamvu, mtundu wosasinthika, mitundu yosiyanasiyana yazogulitsa komanso kuwongolera kwamakampani athu kukhwima komanso kuwongolera ntchito zathu. Tikufuna kugawana malingaliro athu ndi inu ndikulandila ndemanga ndi mafunso anu.
