By using the toxicity of chemical analogues of the amino acids isoleucine and leucine as selection pressure, they were able to augment production of 2-methyl-1-butanol and 3-methyl-1-butanol, respectively, during fermentation. Further purification is possible with this procedure: shaking the product with hot , separating the oily layer, drying the product with , and distilling it, collecting the fraction boiling between 128 and 132 °C. Campinas, 24 2 , 2004, 212-216. Combustion and Flame 2015, 162 9 , 3197-3209. Stereoisomers In drawing stereoisomers, we typically keep the main carbon chain in the plane of the paper and then draw the substituent either up as a wedge or down as a dashed line.
