The solubility curves for ethyl acetate are shown in Figures 18-20, and are representative of methyl acetate, methylbutanoate, ethyl proprionate, isopropyl acetate, butyl acetate, isoamyl acetate, ethyl-2-methylproprionate and butanoic acid
. These esters were unique in that the solubility potentials for PPS and PET increase with increasing blend concentration as shown in Figure 18.
Small chain fatty acids such as propanoic and butanoic acids
were produced from day 2 whereas big chain fatty acids like heptanoic and hexanoic acids were produced from day 5 in all cacao cultivars.
Trimethylamine (a fishy odor), 2-methylpropanal (a malty, dark chocolate odor), 3-methylbutanal (a malty, dark chocolate odor), acetic acid (a sour odor), propanoic acid (a cheesy odor), 2-methylpropanoic acid (a cheesy odor), butanoic acid
(a cheesy odor), 3-methylbutanoic acid (cheesy, sweaty odors) and methional (a cooked potato odor) had the highest odor activity values--greater than 100.
aegypti showed potential larvicidal property which might be due to the presence of various phytochemical constituents such as propanoic acid, butanoic acid
, benzene acetic acid, 4-(1,1-dimethylethyl)-methyl ester, phthalic acid, hexadecanoic acid, 1,2-benzendicarboxylic acid and 9-octadecenamide which may cause degeneration of the pupal alterations in the respiratory system of mosquito larvae, and reproductive system (28-29, 31).
2-(5-Amino-5-chloro-2-oxo-1, 2-dihydrospiro (indole-3, 3-(1, 2, 4) triazol)-4(2H)-yl)-5-(methylsulfanyl) butanoic acid
Effects of liquid DL-2-hydroxy-4- methylthio butanoic acid
on growth performance and immune responses in broiler chickens.
coli O157:H7 included carboxylic acids (hexanoic, pentanoic and butanoic acid
), one aldehyde (benzeneacetaldehyde) and one alcohol (1,2 propanediol).
For example, there are differences in the concentration of aromatic compounds, such as ethyl propanoate ('fruity'), 2-methyl butyl acetate ('banana'), hexyl acetate ('lolly') and 3-methyl butanoic acid
Examples are butanoic acid
and phenyl acetic acid (previously identified in palm wine samples by means of ADA as well as AEDA), acetic acid, methyl propanoic acid, pentanoic acid, and 3-methylpentanoic acid (previously identified by AEDA only).
A high level of ethyl acetate and butanoic acid
ethyl ester (pineapple fragrance) was produced by the two cultures (Table 5).
Pigs fed antibiotics or 0.5% ACTIVATE Starter DA was a dry organic acid blend composed of calcium salt of 2-hydroxy-4-[methylthio] butanoic acid
, fumaric acid, benzoic acid, and carrier with 31% L-met activity) showed the same improvements in weight gain and feed efficiency as those fed a control diet .
PC1 also separated the wine from the nonextracted wine without pectase, based on alcohols (butanol and 3-methylthiopropanol), acids (isobutyric and butanoic acid
), and esters (ethyl 3-hydroxybutyrate and butyrolactone).

Metabolix and university co-researchers also presented technical papers on characterizing melt fracture when extruding poly(hydroxy butanoic acid
) (PHB) copolymers; on the post-fabrication properties of PHB; and on the biodegradability of PHB agricultural mulch film--a potential alternative to polyethylene mulch films.
(1995) found that DH drying of red oak produced identifiable amounts of butyrolactone, butanoic acid
, 2-chloro-butanoic acid, and bis(2-ethylhexyl)phthalate in kiln condensate samples.
