Methanol-driven esterification of volatile short-chain fatty acids in thermal desorption-based analysis [PDF]

open access: yesCommunications Chemistry
Breath volatile organic compound analysis can non-invasively detect diseases, with short-chain fatty acids (SCFAs) identified as key biomarkers. However, SCFA quantification is technically challenging due to chemical instability during thermal desorption

Impregnated Zeolite as Catalyst in Esterification Treatment from High Free Fatty Acids Palm Oil Mill Effluent

open access: yesJurnal Rekayasa Kimia & Lingkungan, 2021
Although Palm Oil Mill Effluent (POME) can be used as a raw material for biodiesel production, the POME contains an excessive amount of Free Fatty Acids (FFA), necessitating a preliminary process and esterification.

Esterification of citric acid with locust bean gum

open access: yesHeliyon, 2019
Esterification of citric acid (CA) with locust bean gum (LBG) was prepared by hydrochloric acid (HCl) as a catalyst and UV irradiation (254 nm) as esterification energy. This study aims to determine the best conditions of esterification. Other than that,

Esterification of p-hydroxybenzoic acid with glucose using a γ-Al2O3/SO4 catalyst [PDF]

open access: yesPharmaciana, 2019
Esterification of p-hydroxybenzoic acid with glucose can be expected to produce esters. The rate of esterification reaction is usually very slow and, therefore, needs an acid catalyst to accelerate it.
