TY - JOUR N2 - Chemical interesterification of rubber seed oil has been investigated for four different designed orifice devices in a pilot scale hydrodynamic cavitation (HC) system. Upstream pressure within 1â??3.5 bar induced cavities to intensify the process. An optimal orifice plate geometry was considered as plate with 1 mm dia hole having 21 holes at 3 bar inlet pressure. The optimisation results of interesterification were revealed by response surface methodology; methyl acetate to oil molar ratio of 14:1, catalyst amount of 0.75 wt. and reaction time of 20 min at 50 °C. HC is compared to mechanical stirring (MS) at optimised values. The reaction rate constant and the frequency factor of HC were 3.4-fold shorter and 3.2-fold higher than MS. The interesterified product was characterised by following EN 14214 and ASTM D 6751 international standards. © 2017 Elsevier Ltd KW - Cavitation; Fluid dynamics; Hydrodynamics; Oils and fats; Orifices; Rate constants KW - Hydrodynamic cavitations; Interesterification; Optimisations; Process intensification; Rubber seed oil KW - Rubber KW - acetic acid; rubber; rubber seed oil methyl ester; unclassified drug; vegetable oil; rubber KW - catalyst; cavitation; hydrodynamics; optimization; reaction rate; response surface methodology; rubber KW - Article; catalyst; controlled study; geometry; Hevea brasiliensis; hydrodynamic cavitation system; hydrodynamics; interesterification; nonhuman; plant seed; pressure; priority journal; rate constant; reaction analysis; reaction time; reactor; response surface method; catalysis; Hevea; hydrodynamics; plant seed KW - Hevea brasiliensis KW - Catalysis; Hevea; Hydrodynamics; Plant Oils; Rubber; Seeds ID - scholars9347 UR - https://www.scopus.com/inward/record.uri?eid=2-s2.0-85015774660&doi=10.1016%2fj.biortech.2017.03.046&partnerID=40&md5=e3a6fc550676abfbf3fe8664e267ae39 A1 - Bokhari, A.
