Critical review of relations for predicting the normal freezing point of organic compounds

Abstract

This paper presents empirical relations for predicting the normal freezing point of organic compounds. Nine relations were tested with 90 organic compounds. The Meyer-van der Wyk and Kreglewski-Marano-Holder models are recommended for normal alkanes, and the Constantinou-Gani and Wen-Qiang II models for all tested organic compounds.

U ovom radu je dat prikaz modela za predskazivanje normalne temperature mržnjenja Tf organskih supstanci. Prikazano je 9 modela, koji su testirani pa 90 organskih supstanci, koje pripadaju različitim grupama jedinjenja. Na osnovu dobijenih rezultata preporučuju se za korišćenje Meyer-van der Wyk i Kreglewski-Marano-Holder modeli za normalne alkane, a za sve testirane supstance Constantinou-Gani i Wen-Qiang II.
