3.5.5- Trimethyl Hexanal

Dimethylamine was added dropwise to formic acid and heated to 60 °C. One equivalent of 3,5,5-trimethyl hexanal was added dropwise over the course of one hour, and the reaction mixture heated until no Anther carbon dioxide was evolved (about one hour). The reaction mixture was poured onto dilute HC1 and washed with ether. The aqueous layer was basified with aqueous NaOH and extracted with diethyl ether. The combined extracts were concentrated in vacuo to yield an orange oil, which was distilled to a colourless oil, 84%. 

Based on the chromatographic analysis, hydrocarbons 1 through 4 are isobutane and C4 olefins hydrocarbons 5 through 17 are major C5 through Ca isoparaffins found in alkylate and hydrocarbon 18 is 2,2,5-trimethyl hexane.
