For instance, the 1,3-butylene glycol based derivative, monocarboxylic acid monoester
, is an excellent plasticizer used in the production of PVC and other plastics.
Twenty healthy individuals participated in the study and on two occasions consumed the ketone monoester
supplement or a placebo after a 10-hour fast.
Conventional phosphorylation could produce monosubstituted phosphate monoester
starch or cross-linked phosphodiester starch.
In a round bottom flask (100 mL), monoester
1 (0.61 g, 3 mmol), EDC (0.74 g, 3 mmol x 1.3 eq.), and catalytic amount of DMAP were placed under nitrogen.
Quantification of P species was done by spectra deconvolution analysis based on the chemical shift, peak width, and peak area, which proved to be successful in particular for areas such as the monoester
region containing a number of peaks, sometimes overlapping; the relative P concentration in the NaOH-EDTA extracts was estimated, based on the total NMR signal area, and presented as percentages of each specie or group of species.
DCHP was measured at a concentration of 0.07 [mu]/[m.sup.3] in samples of indoor air from houses in Japan (6), and its monoester
metabolite was found in the urine of adults of the U.S.
* Hydroxy functional triglyceride polymer with glycerol monoester
and l,l'-methylenebis[4-isocyanatobenzene] (P-16-330) and Hydroxy functional triglyceride polymer with glycerol monoester
and 1,1'-methylenebis[isoc yanatobenzene] (P-16-331) (generic) used as adhesives.
Rubber composition prepared by blending at least one rubber component selected from a natural rubber and/or a diene base synthetic rubber with silica and a glycerin fatty acid ester composition, wherein a blend amount of the glycerin fatty acid ester composition is 0.5 to 15 parts by mass based on 100 parts by mass of the rubber component; the fatty acid has 8 to 28 carbon atoms; the glycerin fatty acid ester composition contains glycerin fatty acid monoester
and glycerin fatty acid diester; and a content of the glycerin fatty acid monoester
in the glycerin fatty acid ester composition is 85% by mass or less.
The generated free radicals caused disproportionation reaction to produce saturation and unsaturation monoester
. The reaction processes and products of the cracked C-C bond at different positions will be consequently discussed with the basis of GC/MS analysis.
DEHP is rapidly hydrolyzed to its monoester
, monoethylhexyl phthalate (MEHP), which is a minor urinary metabolite of DEHP.
Internal exposure of general population to DEHP and other phthalates--Determination of secondary and primary phthalate monoester
metabolites in urine.
Early studies utilising solution [sup.31]P nuclear magnetic resonance (NMR) analysis indicated preferential mineralisation of organic P with diester linkages over organic P with monoester
linkages (Tate and Newman 1982; Hawkes et al.
