Methyl Colza Oil Acid Ester with the Saponification Value

Methyl colza oil acid ester is light yellow oil liquid with the saponification value 180-195mgKOH/g and the  iodine value 100-115gI2/100g(MAX).It is use in auxiliary for light textile.
The polyol, trimethylolpropane (2-ethyl-2-hydroxymethyl-1,3-propanediol), and a smorgasbord of rapeseed vegetable oil greasy acid methyl esters constituted transesterified from immobilised lipases without additional organic dissolving agent. The spiritual rebirth to the polyol tri-ester with immobilized Rhizomucor mieheilipase Lipozyme IM 20 was about 75% after 24 h at 58°C, 5.3 kPa, with no added water, and the drunkest conversion of most 90% lived gained fashionable 66 h.
Cetane numbers rate the ignition holdings of Rudolf Diesel fuels, but as octane Book of Numbers determine the quality and value of gas (gasoline). They're a measuring rod of a fuel's willingness to ignite when it's compressed. The higher the cetane number, the more efficient the fuel. Biodiesel induces a more advanced cetane more petrified than petrodiesel because of its oxygen content.
