A STUDY ON TEMPERATURE OPTIMIZATION OF QUINIZARINE OBTAINMENT

In this study, it was investigated the effect of temperature on obtainment of quinizarine, which is an important raw material for textile dystuffs based on anthraquinone. For this purpose, the experiment was performed at three different temperature in laboratory. Melting points of products obtained were observed and they were analyzed by IR spectrometer. In this way, optimum temperature conditions were determined. At the end of the work, it was observed that the highest yield was obtained at the experiment in which the temperature is gradually increased and then, maintained at 250 °C.

KÝNÝZARÝN ELDESÝ ÝÞLEMÝNÝN SICAKLIK OPTÝMÝZASYONU ÜZERÝNE BÝR ÇALIÞMA

Bu çalýþmada antrakinon esaslý tekstil boyarmaddeleri için önemli hammaddelerden birisi olan kinizarinin eldesi üzerine sýcaklýðýn etkisi araþtýrýldý. Bu amaçla laboratuvar þartlarýnda üç farklý sýcaklýkta deney gerçekleþtirildi. Elde edilen ürünlerin erime noktalarý tayin edildi ve IR spektrumlarý çekildi. Bu tarzda optimum verim için sýcaklýk þartlarý belirlenmeye çalýþýldý. Yapýlan deneyler sonucunda, en yüksek verime kademe kademe arttýrýlarak 250°C' da gerçekleþtirilen deney þartlarýnda ulaþýldýðý gözlendi.
