An optimization experiment, using a Taguchi L9 experimental layout, was used to examine the effect of temperature, pressure, HA:NPG ratio and catalyst amount. The effects of pressure (0.5, 25 and 50 kPa); temperature (423, 453 and 483 K); catalyst amount (0.5, 1.0 and 1.5 w/w) and HA:NPG ratio (1.5:1, 3:1 and 6:1) were investigated and found to have impacts on the reaction. The percentage contribution of each factors are 43.9, 38.8, 4.3 and 12.9 , respectively. At the optimal reaction conditions of 423 K, 0.5 kPa, sulfuric acid catalyst 0.5 w/w and HA:NPG ratio (3:1) more than 99 w/w neopentyl glycol ester was obtained. Confirmation experiments were performed to demonstrate the effectiveness of this approach and characterization of neopentyl glycol ester was characterized using FTIR and 1H NMR. date: 2013 publisher: Chemical Publishing Co. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84886627440&doi=10.14233%2fajchem.2013.14362&partnerID=40&md5=0910a22fa4636e82e5ad7f4da1a1848f id_number: 10.14233/ajchem.2013.14362 full_text_status: none publication: Asian Journal of Chemistry volume: 25 number: 15 pagerange: 8256-8260 refereed: TRUE issn: 09707077 citation: Kamil, R.N.M. and Yusup, S. and Ismail, L.
