Taw qhia rau Synthetic Organic Pigments

Synthetic organic pigments, ua los ntawm cov khoom siv ntawm cov thee tar distillation, yog qhov tshwm sim ntawm cov organic chemistry nyob rau hauv lub thib ob ib nrab ntawm lub xyoo pua 19th, ua raws li los ntawm kev txhim kho ntxiv thiab tshiab inventions nyob rau hauv lub xyoo pua 20th. Hauv kev tsim khoom, hluavtaws dyes yog superior rau thiab hloov cov qub ntuj dyes, tab sis kuj yog lub teeb-resistant thiab tsis haum rau cov paintings ntev.
Hauv kev tsim khoom, hluavtaws dyes yog superior rau thiab hloov cov qub ntuj dyes, tab sis kuj yog lub teeb-resistant thiab tsis haum rau cov paintings ntev. PERKIN'S VIOLET yog thawj cov xim zoo li no (1856), thiab ntau lwm tus ua raws. Txog thaum xyoo 1950, tsuas yog peb cov organic dyes, alizarin crimson, phthalocyanine, thiab phthalocyanine ntsuab, tau pom zoo rau kev pleev xim tas mus li. Coal tar extraction xim thiab aniline xim yog feem ntau siv pigments. Txij thaum ntawd los, ntau cov xim hluavtaws tau siv rau kev pleev xim tas mus li.
