Esterification of butanol in a two‐phase liquid‐liquid system. PART I: Quaternary phase equilibria studies

Abstract

The phase equilibria of the systems a r e discussed:(i) n-butanol-acetic acid-water and n-heptane (ii) Water-acetic acid-benzene and carbon tetrachloride (iii) Water-methanol-p.cresol and methyl naphthalene have been studied and a correlating procedure has been developed that utilize5 binary and ternary experimental data to predict the composition of the quaternary equilibrium mixtures. Allowance is made for the different salting effects and the agreement between the experimental and predicted quaternary data is in all cases very good.

Phase behavior of olive and soybean oils in compressed propane and n-butane

“…Generally, the oil transformation in industrial scale is commonly accomplished by an acid or base-catalyzed reaction. However, yields reported as well as the quality of the products are usually low (Al Saadi and Jeffreys, 1981).…”

Influência das variáveis de processo na alcoólise enzimática de óleo de mamona

“…Ácido sulfúrico é comumente utilizado para esta função; infelizmente, ele geralmente leva à formação de subprodutos indesejáveis que podem ser difíceis de serem separados e recuperados do produto [2]. Além disso, neste caso, parte-se de um substrato (ácido graxo) que possui, também, alto valor.…”

Feasibility studies and dynamics of catalytic liquid phase esterification reactions in a micro plant

“…In this study we focus on the heterogeneously catalyzed synthesis of butyl acetate in a micro system as a model reaction. Since butyl acetate is an important chemical substance for industrial applications a lot of data about the kinetics of this reaction are available from studies using conventional equipment [15][16][17]. The study of the homogeneously catalyzed butyl acetate synthesis in a micro reactor has already been discussed in previous work [18].…”
