“…17,18 The esterication of alcohols with carboxylic acids in acidic chloroaluminate IL was investigated by Deng et al 19 Moreover, the esterication of alcohols with acid anhydrides in the presence of basic or acidic catalysts, such as 4-pyrrolidinopyridine and H 2 SO 4 , has been previously reported. 20,21 Lee et al 22 employed the metallic Lewis acids, such as Cu(OTf) 2 , Sc(OTf) 3 , Yb(OTf) 3 , and In(OTf) 3 , as catalysts in ILs to catalyze the ester-ication of alcohols with acetic anhydride. However, these catalysts suffer from some limitations such as long reaction time, low conversion rate, and lower yield.…”

Further, the ZSM-5 zeolite membrane could allow for selectively permeation of water from high acetic acid concentrated aqueous mixture by pervaporation in our previous studies (Zhu et al, 2016b). In order to raise the production efficiency and economize the production cost, the excess of acetic acid could be supposed to enhance the isoamyl acetate yield of the esterification in this work.…”

“…The PV-esterification apparatus was identical with our previous work (Zhu et al, 2016b). A certain amount of acetic acid, isopentanol and catalyst were added to a 150-mL three-necked flask equipped with a condensing tube, and the flask was heated to a certain temperature (80-110°C) by an oil bath.…”

“…Hasegawa et al (2012) applied the CHA-type zeolite membrane to the esterification of adipic acid and isopropyl alcohol with H 2 SO 4 catalyst, whereby the yield of diisopropyladipate was enhanced from 56 to 98% by the membrane assistance. The mordenite membrane was inserted into the reaction mixtures for the esterication of acetic acid and alcohol using the H 2 SO 4 as catalyst in our previous study, and continuously removed water from the esterication mixtures by pervaporation (PV), which could make a significant increase in alcohol conversions of esterfication (the ethanol and n-butanol conversion of esterfications reached 98.13% and 98.73% at low reaction temperature) (Zhu et al, 2016b).…”

A high performance ZSM-5 zeolite membrane is applied to remove H 2 O from the esteri cation of acetic acid and isopentanol by pervaporation. The in uences of reaction conditions on the isoamyl acetate yield are studied in detail. Compared with the traditional esteri cation of acetic acid and isopentanol, the esteri cation with "membrane extractor" has a well isoamyl acetate yield at low reaction temperature. With the reaction temperature, acetic acid/isopentanol molar ratio and e ective membrane surface area to esteri cation mixture ratio volume of 100°C, 3.0/1.0, 2.0 wt% NaHSO 4 , and 0.26 cm 2 /cm 3 , respectively, the isoamyl acetate yields was 98.39%, the membrane ux and separation factor (H 2 O to organic) were 0.21 kg·m 2 ·h 1 and 1040, respectively. Further, the ZSM-5 zeolite membrane shows good long-term stability and reproducibility for the pervaporation-esteri cation, the isoamyl acetate yields of the esteri cation-pervaporation for intermittent 8 times or continuous 160 h still remained at 97.73% and 98.30%, respectively. In addition, the ZSM-5 zeolite membrane still retained the typical MFI di raction peaks and morphology by XRD and SEM characterization after long-term PV-esteri cation .

“…Esterification of carboxylic acids and alcohols is a typical thermodynamic controlled reversible reaction. In general, the methods of improving the reaction conversion rate involve excess addition of one reactant or removal of the product water by adding water absorbents or distillation . However, these methods have many disadvantages, like high energy consumption and separation difficulty.…”

An active and stable catalytic composite membrane (CCM), poly(vinyl alcohol)–poly(styrene sulfonic acid)/sodium alginate–poly(vinyl alcohol) (PVA‐PSSA/SA‐PVA), was prepared to enhance the esterification of ethanol and propionic acid. The morphologies and crystal structures of the CCMs were investigated by Fourier transform infrared spectroscopy, scanning electron microscopy, and X‐ray diffraction. The effects of catalytic layer thickness, mass ratio of PVA to PSSA, concentration of catalytic layer solution, ratio of reaction volume to membrane area, and molar ratio of propionic acid to ethanol were discussed. The pervaporation results showed that the flux of CCM increased from 118 to 320 g m−2 h−1 compared with the SA‐PVA membrane because of the close affinity and low resistance of PSSA to water. After crosslinking with 3‐aminopropylmethyldiethoxysilane, the CCMs had good catalytic activities. The acid conversion reached 92.8% at 75 °C in 12 h, and the stabilization of the CCM was greatly improved. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46514.
