STUDY OF PHASE EQUILIBRIA IN SYSTEM HEXADECANE - DOCOSANE – CYCLODODECANE

Ternary n-hexadecane - n-docosane - cyclododecane system was studied with the method of a differential thermal analysis. The studied system concerns to systems of eutectic type. The eutectic composition melting at 7.3 °С and containing 65.0 wt. % n-hexadecane, 6.5 wt. % n-docosane and 28.5 wt. % cyclododecane was revealed.

Key words: n-alkane, cyclododecane, ternary system, docosane, heat carrier

RESEARCH OF STABLE TETRAHEDRON OF LiF-LiVO3-NaBr-NaVO3 QUATERNARY MUTUAL SYSTEM OF Li,Na||F,Br,VO3

Phase equilibria of quaternary system LiF-LiVO3-NaBr-NaVO3 were studied with differential thermal analysis method. The temperature and composition of eutectic point was determined: Е 458 ºС: 11.2% LiF, 57.2% LiVO3, 16% NaBr, 15.6% LiVO3.

Key words: phase equilibria, T-x diagram, differential thermal analysis (DTA), stable tetrahedron, eutectic
