The physicochemical properties of CPO are shown in Table 1.
The CPO density was measured using an Anton Paar DMA5000
instrument (meet ASTM D4052-96 (2002)), kinematic viscosity
was determined using an Ubbelohde glass viscometer while the
FFA content was determined by means of the acid value using
the official method Cd 3d-63 (A.O.C.S., reapproved 1997). Agilent
Hewlett-Packard 6890 series gas chromatograph was used, which
was equipped with flame ionization detector, SP-2340 capillary column
(60 m in length, 25 mm of internal diameter, and 0.2 m film
thickness) and a split ratio of 100:1 (A.O.C.S., reapproved 1997).
and without drying or any further purification.
