1. Experimental study on the excess molar enthalpy of binary liquid solutions containing 1-pentanol + acetonitrile and 1-hexanol + acetonitrile at different temperatures and atmospheric pressure and correlation of data using PFP and ERAS models / Estudo experimental da entalpia molar em excesso de soluções liquidas binarias contendo 1-pentanol ou 1-hexanol e acetonitrila a diferentes temperaturas e pressão atmosferica e correlação atraves dos modelos PFP e ERAS
This work is focused on the experimental study of the excess molar enthalpy as a functions of composition of binary liquid solutions containing 1-pentanol + acetonitrile and 1- hexanol + acetonitrile for 288,15, 298,15, 313,15 and 323,15K and atmospheric pressure. The excess molar enthalpy was calculated using colorimetric method. To accomplish this purpose

2. Imobilização de etilenimina, etilenossulfeto, 2- aminoetanotiol em silica gel - termodinamica das interações dos centros basicos nitrogenio e enxofre com cations em solução aquosa
The silylating agent 3-mercaptopropyltrimethoxysilane (MPTS) grafted onto silica gel was subsequently condensed with one molecule of ethylenimine (etn). In the homogeneous route, etn and MPTS reacted to yield 3-trimethoxypropylthioethylamine (MPTS), which was covalently anchored on silica gel. The dired reaction of silica and etn gave Sil(CH2CH2NH)4CH2CH2NH2
