Mawu Oyamba

Solvent Yellow 18 ndi chosungunulira cha organic chokhala ndi dzina lamankhwala la 2-chloro-1,3,2-dibenzothiophene.

 

Solvent Yellow 18 ili ndi izi:

1. Maonekedwe: yellow crystalline powdery olimba;

4. Kusungunuka: Kusungunuka mu zosungunulira za polar organic, monga ethanol, ethers ndi chlorinated hydrocarbons.

 

Ntchito zazikulu za zosungunulira zachikasu 18:

1. Monga utoto wapakatikati: zosungunulira zachikasu 18 zitha kugwiritsidwa ntchito popanga utoto, ndipo zimagwira ntchito yofunika pakupaka utoto wa nsalu, mapepala kapena pulasitiki;

2. Monga zosungunulira: Ili ndi solubility yabwino ndipo ingagwiritsidwe ntchito ngati zosungunulira muzochitika za organic synthesis.

 

Kukonzekera njira ya zosungunulira yellow 18:

The zosungunulira yellow 18 akhoza kupangidwa ndi zimene benzothiophene ndi chloroacetyl kolorayidi, ndiyeno analandira ndi chothandizira zochita za cuprous kolorayidi ndi iridium carbonate.

 

Zambiri Zachitetezo cha Solvent Yellow 18:

1. Zosungunulira zachikasu 18 zimakhala ndi zowawa zina ndi kawopsedwe, zomwe zingayambitse kupsa mtima komanso kusapeza bwino pokhudzana ndi khungu ndi kupuma;

2. Chisamaliro chiyenera kutengedwa kuti musagwirizane ndi khungu ndi maso mukamagwiritsa ntchito, ndikuwonetsetsa kuti ntchitoyo ikuchitika pamalo abwino;

3. Mukakhudza kapena kumeza mwangozi, muzimutsuka mwamsanga ndi madzi ambiri ndikupita kuchipatala nthawi yake;

4. Posunga, ziyenera kusindikizidwa ndi kusungidwa pamalo ozizira, owuma kuti zisakhudzidwe ndi oxidant amphamvu ndi asidi amphamvu.
