Rape straw (Brassica napus) was used to prepare high-quality biocrude (ORS) through thermochem. liquefaction. The effects of liquefaction temperature, solid-liquid ratio (R1), and solvent filling ratio (R2) on the yield of ORS prepared from rape straw were studied. The yield of ORS reached the maximum value (22.11 %) at 340 °C, with R1 10 % and R2 20 %. GC-MS anal. indicated that at low liquefaction temperatures (>300 °C) the compounds in ORS were mainly esters, whereas at higher temperatures they were mainly phenolic compounds Anal. based on the b.ps. indicated the presence of mainly C8, C9, and C20 compounds Elemental anal. and measurement of the higher heating value (HHV) showed that the HHV of ORS at 340 °C was 41.36 MJ/kg. The process described in this work not only effectively disposes of rape straw, but also converts it into a potential renewable transportation energy alternative. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Reference of 499-75-2).
5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Reference of 499-75-2
