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

Intangiriro

Nibintu kama. Inzira ya molekuline ni C8H5NO2, formulaire ni HO-C6H3 (CN) 2.

ni ibara ritagira ibara rifite impumuro nziza ya fenol. Ifite ahantu hanini cyane gushonga no gutekesha, gushonga mumashanyarazi kama nka ethers, alcool na ketone, idashonga mumazi.

Imikoreshereze nyamukuru yuru ruganda ni nkingirakamaro hagati muri synthesis. Irashobora gukoreshwa muguhuza polyester nshya kugirango hategurwe ibikoresho bya optique, electronique na farumasi. Mubyongeyeho, irashobora kandi gukoreshwa nkibikoresho fatizo bifatika bifatika.

Uburyo bwo gutegura inzira buragoye. Bumwe mu buryo bw'ingenzi ni reaction ya p-fenolate sulfate hamwe na sodium cyanide mu bihe bya alkaline kugira ngo ibe 4-hydroxy-2-fenylbenzonitrile, hanyuma ikabonwa na acide-catisale ya decarboxylation.

Mugihe ukoresha no gutunganya, ugomba kwitondera ibibazo byumutekano. Ifite uburakari runaka, irinde guhuza uruhu no guhumeka. Ibikoresho bikwiye byo gukingira, nka gants ya laboratoire nibikoresho birinda ubuhumekero, bigomba kwambarwa mugihe gikora. Byongeye kandi, guhura na okiside hamwe na acide zikomeye bigomba kwirindwa kugirango wirinde ingaruka mbi. Mugihe cyo kubika, irinde inkomoko yumuriro nubushyuhe, kandi ugumane kontineri ifunze kugirango wirinde guhindagurika no gutemba.
