Methyl-tributyl ether

TWO organometallic polymers previously developed, tributyl-tin methaczylate/methyl methacrylate copolymer (TBTM/MeM) and the tributyltin ester of methyl vinyl ether/maleic anhydride (TBT-MVEt-MAn), were selected for use as wood impregnants. Full Cell and Enpty Cell Methods were used to treat wood with TBTCVMeM in "Rule 66" mineral spirits and in combination with P13 creosote. Although the polymers seem to be miscible with the creosote, this combination results in only surface penetration of wood when...

The reaction between 5-methyl-2-(l-methyl-1 -phenylethyl)cyclohexyl 2-oxoacetate and 2-buteny](tributyl)stannane promoted by boron trifluoride-diethyl ether complex showed a strong preference for 57-facial attack, with syn selectivity69. 

Like Still s reagent, tributyl[(methoxymethoxy)methyl)etannane incorporates an alcohol protective group that can be conveniently unmasked under mild acidic conditions. However, an advantageous feature of this MOM ether derivative is that, in contrast to Still s reagent, it is achiral. In many applications the introduction of an additional chiral center into synthetic intermediates is undesirable because of the complications associated with the manipulation, analysis, and purification of diastereomeric mixtures.

Certain antifoams, for example, methyl or ethyl alcohols, when introduced in the foaming solution, affect indirectly the foam stabilising properties of the adsorption layers because they change either the surfactant solubility or its CMC. It has been established [39] that addition of antifoams (2-ethylhexanoI and tributyl phosphate) increases CMC. Schick and Fowkes [40] have observed a certain change in CMC of NaDoS when tetradecanol is added. If the compounds added improve the foaming ability (such as dodecylglycol ether and (3-hydroxyethyl laurylamide), CMC decreases. 

Actinide ions form complex ions with a large number of organic substances (12). Their extractability by these substances varies from element to element and depends markedly on oxidation state. A number of important separation procedures are based on this property7. Solvents that behave in this way are tributyl phosphate, diethyl ether [60-29-7 ], ketones such as diisopropyl ketone [565-80-5] or methyl isobutyl ketone [108-10-1 /, and several glycol ether type solvents such as diethyl Ceflosolve [629-14-1] (ethylene glycol diethyl ether) or dibutyl Carbitol [112-73-2] (dietliylene glycol dibutyl ether). 

The 4-hydroxyl of 8,9-0-isopropylidene derivative 4b has been protected as its 4-t-butyl-dimethyl-silyl ether 4e. Then, the 7-hydroxyl has been converted to its xantate ester 4f, by deprotonation with butyl litium, treatment with carbon disulfide and alkylation with methyl iodide. Deoxygenatiobn of the 7-position has been accomplished by heating with tributyl-tin hydride in xylenes. Then, the cleavage of acetonide and of silyl ether, by heating in 80% acetic acid, followed by hydrogenolysis to remove the benzyl ester, afford 7-deoxy-Neu%Ac-ctMe Im. 

The next step in purification is separation of uranyl nitrate from the other metallic impurities in the dissolver solution by solvent extraction. Practically aU uranium refineries now use as solvent tributyl phosphate (TBP) dissolved in an inert hydrocarbon diluent. The first U.S. refinery used diethyl ether as solvent and later refineries have used methyl isobutyl ketone or organic amines, but practically all have now adopted TBP. It is nonvolatile, chemically stable, selective for uranium, and has a uranium distribution coefficient greater than unity when the aqueous phase contains nitric acid or inorganic nitrates. 

Cations that complex easily generally form stable complexes with oxygenated organic compounds, such as diethyl ether, methyl isobutyl ketone, and tributyl phosphate (TBP). The purification of uranium by solvent extraction of hexavalent uranium from nitrate solutions, with TBP forming U02(N03)2 2TBP, was described in Chap. 5. These metals are extracted most easily from aqueous solutions free of the more hi y complexing anions, such as F, P04, or S04 . 

Selective benzoylation (and allylation) of methyl (and benzyl 4-O-benzyl-a-L-rhamnopyranoside (4) has been studied by phase-transfer catalysis and by activation via the tributyl stannate. The former reaction gave the 2,4-dibenzyl ether (5) in high yield, whereas the latter process gave mainly the 3,4-diether (6). An alternative means of obtaining the 2,4-diether (5) involved selective tritylation to give (7) followed by benzylation and removal of the trityl group. These dibenzyl ethers have been employed in the synthesis of the tetrasaccharide repeating unit of the immunodeterminant of Klebsiella serotype K36 polysaccharide. Similar results have been recorded for the selective benzylation of other 4,6-blocked a-mannosides. The syntheses of 3-O-benzyl-D-ribose, 2-0-benzyl-D-ribose, and l,6-anhydro-2,3,2, 4-tetra-0-benzyl-jS-lactose have been recorded. The latter was employed in the synthesis of lacto-A -tetraose. ...
