Hydrolysis rapid

Carbamic acid [463-77-4] NH2COOH, is the hydrated form of isocyanic acid [75-13-8] H—N=C=0. It is not known in the free state hydrolysis rapidly gives ammonia and carbon dioxide. [Pg.434]

Stable at pH 5, moderately stable at pH 7 and 9 Undergoes hydrolysis rapidly. The half-life ti/2) of carfentrazone-ethyl in aqueous photolysis at pH 5 is... [Pg.475]

Rate of hydrolysis Rapid for vapor and dissolved Lewisite L-2. Low solubility in water limits the hydrolysis. [Pg.12]

The phase-I metabolism of bambuterol is complex and involves both oxidation and hydrolysis. In human plasma, hydrolysis rapidly yields the monocarbamate metabolite, and then, slowly, terbutaline [164a], The reaction is catalyzed mainly by the nonspecific cholinesterase (EC 3.1.1.8) found in plasma [166]. In addition, cytochrome P450 catalyzed hydroxylation of an... [Pg.497]

Hydrolysis rapidly hydrolyzed in acidic media (Hartley Kidd 198) ... [Pg.890]

Beclomethasone dipropionate is stated to be readily absorbed from sites of local application and rapidly distributed to all body tissues. It is metabolized principally in the liver, but also in other tissues including the gastrointestinal tract and the lung enzymatic hydrolysis rapidly produces the monopropionate, and more slowly, the free alcohol, which is virtually devoid of activity. [Pg.428]

The reaction between Re2Ov(thf)2 and Bu3SnC=CSnBu3 gives the extremely unstable Re03 2( i-C=C) (52) in quantitative yield (by NMR). Hydrolysis rapidly produces Re03(C=CH), which is further converted to H[Re04].177... [Pg.212]

Poisoning, particularly in children, from the consumption of the kernels of various fruits is not an uncommon occurrence (39). The seeds of such fruits as the apricot, peach, cherry, plum, and almonds are known to contain cyanogenetic glycosides in which the aglycone is D-mandelo-nitrile (40) as exemplified by amygdalin whose structure is shown in Figure 8. Amygdalin itself is harmless as such, but when the seed is crushed and the pulp moistened, enzymatic hydrolysis rapidly ensues with the concomitant release of HCN. [Pg.291]

PROBABLE FATE photolysis photoisomeraization occurs, rate undetermined, photooxidation half-life in air 59 minutes-9.8 hrs, vapor phase hepatchlor in air will react with photo-chemically produced hydroxy radicals, half-life 36 min., direct photolysis may occur oxidation information is not available hydrolysis rapid hydrolysis for heptachlor in solution, first-order hydrolytic half-life 23.1 hrs or 129.4 hrs, significant in moist soils volatilization expected to be an important process, evaporates slowly, release to soil will result in volatilization from the surface, especially in moist soils sorption probably an important process, but no reliable data is available, sticks strongly to soil particles biological processes will bioaccumulate if not hydrolyzed, biodegradation is significant... [Pg.325]

It is an aminopenicillin oral prodrug which gets converted to ampicillin in vivo after imdergoing hydrolysis rapidly in the presence of esterases in plasma. [Pg.749]

Hydrolysis rapidly converts the readily soluble UFe and UCL to UO2F2 and UO2CI2, and PuFe to PUO2F2 and PUOF4. Uranyl phosphate and ores such as car-notite, KU02V04 V2H2O, are practically insoluble. [Pg.79]

The action of acetic anhydride on an a-acylamino acid in aqueous solution yields an azlactone, provided that a basic catalyst, such as sodium acetate, is present. Unsaturated azlactones are prepared readily by this method. Saturated azlactones are obtained in poor yields since they undergo hydrolysis rapidly in aqueous solution. Optically active a-acylamino acids are racemized under these conditions as a result of the temporary formation of the azlactone. ... [Pg.203]
