STUDI KINETIKA REAKSI HETEROGEN α-PINENE MENJADI TERPINEOL DENGAN KATALISATOR ASAM KHLORO ASETAT

KINETIC STUDY OF HETEROGENEOUS HYDRATION OF α-PINENE TO TERPINEOL USING CHLORO ACETIC ACID AS A CATALYST. Indonesian turpentine contains 65-85% αpinene, 1% camphene, 1-3% β-pinene, 10-18% 3-carene and limonene 1-3%. In orde r to obtain more valuable products, α-pinene can be hydrated in dilute acid solutions to produce terpineol, which can be used as perfume, insect repellent, antifungal, d isinfectant etc. The aim of this research was to study kinetics of terpineol synthesis from α-pinene, the main component of turpentine Turpentin e was introduced into a batch reactor (tree neck flask) e quipped with condenser, thermometer, stirrer and was warmed up to the desired temperature with the r eaction time of 420 minutes. The study investigated the effects of temperature, catalyst a mount, and the stirring rate on the hydration of αpinene. The heterogeneous kinetics model was propos ed to quantitavely describe the hydration process of α-pinene. The results of this study showed the relat ionship of the constants of the reaction rate and temperatures. The equations can be written as follo w
