【Alkylation】Properties of alkylated oils
Thread Content
This post was last edited by Xiao Gong 1985 on 2016-2-26 at 13:53. When discussing the properties of alkylated oils, people usually talk about their octane rating; I would like to ask what the density of alkylated oils is
The density of alkylated oil is 0.68–0.7 g/M3; its vapor pressure is 35 KPA； PH neutral ； Free of olefins ； Free of aromatics ； The octane rating is between 95 and 98 ； The initial boiling point is between 28 and 35 ； Dry point below 205 ； Copper corrosion: 1A. Hope this can help you, fellow sea enthusiast
Can the octane rating really reach 95–98? ? The sample we made is 80-85. . . Is there something wrong with our machine? ? ?
Density 0.687---0.695
Density/kg•m-3 (20°C): 0.687–0.695; Resins/mg•(100ml)-1: 0.8–1.3; Corrosion/Cu, 50, 3h: 1a; Sulfur content/ppm: <10; RON: 93–95; MON: 92–93; Vapor pressure/kg•cm²: 54–61; Boiling range/°C: IBP 39–48, 10%: 76–80, 50%: 104–108, 90%: 148–178; FBP: 190–201
It’s a problem with product quality, related to the raw materials. Thank you
It’s possible. . . The external factory standard sample is 95+. . .
Thank you all for your great replies; I now have an understanding of alkylated oils.
The density is 0.69–0.7; the boiling point ranges from 35–40, while we keep the dry point at 195–200. As for the octane rating, the theoretical value can reach 100, but in practice, the value we obtain in our samples is around 90
After alkylation, the main component is isooctane, which has an octane rating of 100; however, there are many by-products, and the higher the octane rating, the more by-products there are Since the octane number of high-octane fractions is below 140 degrees, the octane number of wide-range fractions is generally also above 92.
Who has the startup documentation for alkylation equipment? Please help. yu4938@163.com
