Mesylate and tosylate of ethyl lactate
were the lactic acid derivatives used for the reaction.
Among the new entries are aluminum hydroxide adjuvant, disodium edetate, ethyl lactate
, hectorite, lactose spray dried, lauric acid, linoleic acid, raffinose, and saponite.
Typical resist solvents were propylene glycol methyl ether acetate (PGMEA) or ethyl lactate
has introduced a family of corn-derived ethyl lactate
A very strong chromatographic peak was identified as ethyl lactate
. This material results from the action of the lactobacillus and is responsible for beer's sharp/sour flavor.
Other compounds that were not detectable in the exhaled breath by EXOM-HRGC-O but by ADA or AEDA, respectively, were ethyl lactate
, diethyl succinate, 1-hexanol, 3-methylthio 1-propanol, 2-phenylethanol, vanillin, as well as the furanone compounds 4-hydroxy-2,5-dimethyl-3(2H)-furanone, 3-hydroxy-4,5-dimethyl-2(5H)-furanone, 2-ethyl 3,5-dimethylpyrazine, 2-acetylpyridine, and 4-methoxy-2-methylphenol.
Solid resin solutions in methanol and ethyl lactate
were fractionated by ultracentrifugation and liquid-liquid centrifugation (using water and hexane as non-solvents).
