Dab tsi yog -Naphtholthalein \/ alpha-naphtholthalein?
-Tsis txhob txwm muaj lub npe hu ua Alpha-Naphtholthalein. Nws yog cov organic compound. Nws yog tus liab crystalline khoom. Nws yog insoluble hauv dej ntawm chav tsev kub, tab sis soluble hauv cov kuab tshuaj ethanol thiab chloroform. -Tsis txhob txwm siv dav hauv kev tsom xam tshuaj, tshwj xeeb tshaj yog raws li qhov ntsuas hauv cov kua qaub-hauv paus. Nws tuaj yeem txiav txim siab lub tsev pheebsuab kawg ntawm cov kev daws teeb meem kua qaub thiab cov kev txiav txim siab ua tiav los ntawm cov kev hloov pauv (feem ntau tsis muaj xim nyob rau hauv acidic mob thiab liab nyob rau hauv alkaline tej yam kev mob).

Kev siv
- Acid-paus ntsuas taw qhia: hauv kev tsom xam tshuaj, alpha-naphtholthalein feem ntau siv los ua qhov ntsuas rau cov kua qaub-hauv lub zos. Nws cov xim hloov nrog tus nqi ntawm tus lej ntawm cov tshuaj thiab yog siv los qhia qhov kawg taw tes ntawm cov tshuaj tiv thaiv.
- Tsuas yog siv roj ntsha: hauv kev sim biological, -naphtholthalein tuaj yeem siv ua qhov ntsuas qhov ntsuas rau cov micrtructures (yuav tsum tau hloov kho raws li kev sim ua).
- Organic synthesis Qib Nruab Nrab: -naphtholthalalein kuj tseem siv tau los ua ke, thiab lwm yam kev hloov pauv los ntawm cov pab pawg phenhologyles, thiab cov pab pawg orgroxyl hauv pab pawg.
Cov Ntaub Ntawv Kev Nyab Xeeb
- Alpha-Naphtholthalein yuav tsum raug zam los ntawm kev sib chwv nrog tawv nqaij thiab lub qhov muag thaum lub sijhawm ua haujlwm. Kev ntsuas xws li hnav cov hnab looj tes tiv thaiv thiab cov hnab looj tes tuaj yeem coj mus.
- Nws yuav tsum tau ua haujlwm nyob rau hauv qhov chaw muaj cua zoo kom tsis txhob nqus tau lub vapor.
- -Tsis txhob txwm yog cov khoom siv hluav taws xob thiab yuav tsum muab cia rau qhov chaw txias, qhuav, qhov chaw muaj qhov cua, kom deb ntawm cov hluav taws thiab oxidants.
- Zam kev sib cuag nrog cov muaj zog oxidants thiab muaj zog acids kom tsis txhob muaj kev phom sij.
