CAS: 2144-08-3|2,3,4-Trihydroxybenzaldehyde

Khoom Description

Cov khoom uas sib raug rau CAS No. 2144 - 08 - 3 yog 2,3,4 - Trihydroxybenzaldehyde, tseem hu ua Pyrogallol - 4 - carboxaldehyde. Nws cov mis molecular yog C₇H₆O₄ thiab nws qhov hnyav molecular yog 154.12.

2,3,4 - Trihydroxybenzaldehyde tshwm raws li cov hmoov daj me ntsis crystalline hmoov los yog lub teeb xim av koob zoo li cov muaju. Nws cov ntsiab lus melting ntawm 159 - 161 degree (lit.) lossis 161 - 163 degree, thiab qhov ceev yog 1.598g / cm³.

Hais txog nws cov khoom siv tshuaj, muaj hydrogen bonds nyob rau hauv 2,3, 4 - Trihydroxybenzaldehyde, qhov twg cov 2 - hydroxyl thiab aldehyde pawg tsim intramolecular hydrogen bonds. Nws tuaj yeem dhau los ua cov tshuaj tiv thaiv condensation nrog thawj amines los tsim Schiff hauv paus. Lub caij no, vim muaj cov aldehyde thiab hydroxyl pawg, nws tuaj yeem raug cov tshuaj tiv thaiv xws li oxidation, txo qis, thiab ntxiv cov aldehyde pawg, nrog rau kev hloov pauv thiab esterification ntawm hydroxyl pawg.
