Example 2

A mixture of 8.00 g (95 mmole) trans 3-hexene (GFS Chemicals, Powell, Ohio), 10.30 g (143 mmol) acrylic acid, and 0.50 g (3.3 mmol) trifluoromethanesulfonic acid (Alfa Aesar) was heated to 60° C. for 24 hours. The mixture was cooled to room temperature. Ethyl acetate (50 mL) was added and the mixture was washed with saturated sodium bicarbonate until the aqueous layer was basic. The organic layer was isolated and dried over MgSO₄, then filtered. The solvent was removed under vacuum, then the crude oil was then distilled under reduced pressure. A colorless oil fraction was collected (4.80 g) at 43-44° C. at 8 millimeters of mercury (mmHg). The product is 32 mol % 2-hexyl acrylate and 68 mol % 3-hexyl acrylate (as determined by NMR test method).

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.
