Hemp (Cannabis sativa) seed oil is a rare source of nourishment for vegetarian diets due to the unique ratio of ω-6/ω-3 fatty acid as 3:1. It is beneficial for cardiovascular health, skin, hormonal balance, diabetes, etc. These oil benefits encourage the chem. industries for its intensive extraction to accomplish the quantity and quality of the product. Despite being various processes i.e. supercritical fluid extraction, Soxhlet, percolation, ultrasonication, pyrolysis, pretreatment processes etc., none of above is the best in all aspects. Therefore, the present study investigates different extraction processes for hemp oil and compared its industrial-scale economic assessment, extraction yield, oil compositions and physico-chem. properties. Central composite design was employed to optimize the parameters of supercritical fluid extraction and ultrasonication processes. Quadratic models (P < 0.05) for both processes were developed with satisfactory R2 (>0.93). The maximum yield of 37.30% was estimated through ultrasonication treated Soxhlet process. Gas chromatog.-mass spectrometry demonstrated Soxhlet as the best-suited process while offering the optimum ω-6/ω-3 ratio. Further, gas chromatog.-mass spectrometry of hemp bio-oil obtained through pyrolysis identified the volatile and flammable materials to assure its suitability as bio-fuel. Economic analyses for different processes revealed supercritical fluid extraction as the most beneficial followed by Soxhlet, ultrasonication, ultrasonication treated Soxhlet and Soxhlet treated ultrasonication. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Recommanded Product: 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 2253-73-8
