The cross-coupling of two alkenes also takes place. Alkenes such as acrylate react regioselectively with 1,3-dimethyluracil (290) to afford 5-(l-alkenyl)ura-cils such as 291 in a high yield[260]. [Pg.60]

Ura.nium, The hydrometallurgical treatment of uranium ores is a concentration and purification process. Typical ore grade is 0.1—0.5% U Og, and pregnant solutions contain ca 1 kg/m of U Og. The dissolution requires the presence of an oxidant, either oxygen or a ferric salt. [Pg.172]

FIG. 22-40 Normalized free-energy difference between distributed (II) and nondistributed (I) states of tbe solid particles versus tbree-pbase contact angle (collection at tbe interface is not considered). A negative free-energy difference implies tbat tbe distributed state is preferred over tbe nondistributed state. Note especially tbe significant effect of n, tbe ratio of tbe liquid droplet to solid-particle radius. [From Jacques, Ho-oaron ura, and Hemy, Am. Inst. Cbem. Eng. J., 25 1), 160 (1979).]... [Pg.2017]

A landmark scientific breakthrough resulted from the synthesis and metabohc studies of 5-fluorouracil (5) (fl ura or 5-FU), 5-fluoroorotic acid ( f) (fl oro), and 5-fluorocytosine (7) (fl cyt) by Heideiberger and co-workers [2] Several excellent recent reviews are available on this important field [9, 23, 24, 25, 26 ]. [Pg.1013]

Depending upon lithologic and structural relationship with host rocks, mineralogy, attendant alteration, paragenesis and spatial and temporal constraints, the uranium resources of the world can be assigned to the 15 main categories of uranium ore deposits. They have been shown numerically numbered in sequence in the order of their approximate economic significance in Table 1.18. At present, only 7 can be said to be economically important (see Table 1.19) and these account for more than 95% of the world resources of ura-... [Pg.73]
