Determination of the Solubility Parameters of Biodiesel from Vegetable Oils

Abstract

The fatty acid methyl esters of vegetable oils and animal fats, more commonly known as biodiesel, represent a renewable, biodegradable, noninflammable, and low toxicity alternative to diesel. In this study, the Hansen solubility parameters (HSPs) and the interaction radius of the solute sphere (R 0 ) were determined for the biodiesel derived from soybean oil, coconut oil, palm oil, and castor oil, using 45 solvents and solvent mixtures. The values for the HSPs and R 0 obtained for the different biodiesels were soybean (15.

A Quantitative Multi‐Criteria Solvent Selection Method for Extraction Processes: Case Study—Downstream Purification of Sucrose‐Based Surfactants

“…In order to assess the potential effectiveness of these solvents for MP extraction, the HSP were used as surrogate for solute‐solvent affinity. The HSP and Ro j values for the SE (Yanke et al, ) and MP (Batista et al, ) are reported in Table S1 in the supplementary material. The corresponding HSP of the 19 selected solvents are listed in Table .…”

Compatibility of different biodiesel composition with acrylonitrile butadiene rubber (NBR)

“…The difference between the solubility parameter of a solvent and NBR could then be determined using the D d factor [19].…”

Comparison of Ionic Liquids and Chemical Permeation Enhancers for Transdermal Drug Delivery

“…Existing HSP values (δ D , δ P , and δ H ) available for ILs [ 42–45,47 ] and CPEs [ 48–53 ] are referenced and tabulated in Tables S2 and S3, Supporting Information. For ILs with reported solubility parameters using the modified separation of cohesive energy density method , HSP values were estimated as: δ D = λ, δ P = τ, δ H = .…”

“…While HSP has been measured or can be estimated using software packages based on abundant solubility data for various conventional CPEs, [4,[39][40][41] much fewer HSP values have been reported for ILs/DESs due to the lack of a solubility database and computational methods. We therefore present HSP values available for 27 ammonium-, phosphonium-, amidium-, and imidazolium-based ILs [42][43][44][45][46][47] along with 24 conventional CPEs [48][49][50][51][52][53] on Figure 6. A complete list of values is provided in Tables S2 and S3, Supporting Information.…”
