4-hydroxybenzene-1 3-dicarbonitrile (CAS# 34133-58-9)

Mawu Oyamba

Ndi organic pawiri. Mapangidwe ake a molekyulu ndi C8H5NO2, kapangidwe kake ndi HO-C6H3(CN)2.

ndi cholimba chopanda mtundu chokhala ndi fungo lochepa la phenol. Lili ndi malo osungunuka kwambiri ndi malo otentha, osungunuka mu zosungunulira za organic monga ethers, alcohols ndi ketones, osasungunuka m'madzi.

Kugwiritsidwa ntchito kwakukulu kwa pawiri ndikofunika kwambiri pakati pa kaphatikizidwe ka organic. Itha kugwiritsidwa ntchito popanga ma polyesters atsopano pokonzekera zopangira zamagetsi, zamagetsi ndi zamagetsi. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati zopangira zomatira komanso zokutira.

Njira yokonzekera ndondomekoyi ndi yovuta kwambiri. Chimodzi mwa njira zazikulu ndi zimene p-phenolate sulphate ndi sodium cyanide pansi zinthu zamchere kupanga 4-hydroxy-2-phenylbenzonitrile, amene ndiye akamagwira asidi-catalyzed decarboxylation.

Mukamagwiritsa ntchito ndikugwiritsa ntchito, muyenera kusamala zachitetezo. Ili ndi mkwiyo wina, pewani kukhudzana ndi khungu ndi kupuma. Zida zodzitetezera zoyenera, monga magolovesi a labu ndi zida zotetezera kupuma, ziyenera kuvalidwa panthawi yogwira ntchito. Kuphatikiza apo, kukhudzana ndi oxidizing agents ndi ma acid amphamvu kuyenera kupewedwa kuti mupewe zoopsa. Posungirako, khalani kutali ndi moto ndi magwero a kutentha, ndipo sungani chidebe chotsekedwa kuti chiteteze kuphulika ndi kutayikira.
