Crude Glycerol Liquefaction and Polyurethane Foam Synthesis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Unrefined crude glycerol (CG, GS Caltex, Seoul, Korea) consisting of 80 wt% glycerol, 12 wt% water, and other impurities was used as the liquefying solvent without further purification [18 (link)]. The co-solvent, 1,4-butanediol (BD, Daejung Co., Gyeonggi-do, Korea), was used with the crude glycerol. The acid and base catalysts utilized 95% sulfuric acid (Sam-chun Co., Seoul, Korea) and sodium hydroxide beads (Daejung Co., Gyeonggi-do, Korea), respectively. For the determination of the acid and hydroxyl numbers, ethanol (Daejung Co., Gyeonggi-do, Korea), phthalic anhydride (Tokyo Chemical Industry Co., Tokyo, Japan), pyridine (Sam-chun Co., Seoul, Korea), imidazole (Daejung Co., Gyeonggi-do, Korea), and standard sodium hydroxide (0.1 N and 0.5 N, Daejung Co., Gyeonggi-do, Korea) were used. To synthesize polyurethane foam, poly [(phenyl isocyanate)-co-formaldehyde] (PMDI, Sigma-Aldrich Co., Seoul, Korea) and a preresin mix (PIUSYS, Gyeonggi-do, Korea) were used [19 (link)]. All chemicals were of analytical reagent grade without further purification.

The stainless steel mesh was purchased from Anping County Bolin Metal Wire Mesh Co., Ltd (China). Methylene blue hydrate, titanium oxide (TiO2), span 80, and fluorescein isothiocyanate-dextran (FITC) were purchased from Sigma-Aldrich. Hexadecane (95 %) was purchased from Thermo Scientific. Sodium hydroxide beads, ethyl alcohol (Extra Pure) and acetone (Extra Pure) were purchased from Daejung Chemicals & Metals (South Korea). Hydrochloric acid was purchased from Samchun Chemical (South Korea). All of these were used without further purification. Deionized water (DI water, 18.2 mΩ·cm) was utilized here and obtained from a water purification system (Human Corporation, South Korea).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
