T-butane

Isomers — different structural arrangements with the same chemical formula (e.g., n-butane and t-butane). 

The results for the exchange of t-butane on metal films 18) were similar to those for the exchange of propane. Tungsten causes a slight amount of...

The following data refer to the adsorption of /t-butane at 273 K by a sample of tungsten powder which has a specific surface area (as determined from nitrogen adsorption measurements at 77 K) of 6.5... 

A careful search was made for methyl cyclopropane138 in the photolysis of n-butane and of t -butane with only negative results. The absence of methyl cyclopropane may be due to the great excitation in the carbene produced photochemically, although a better explanation may be that the carbenes produced have a much higher probability of isomerizing to butenes.

A series of analogues of the decamer d(GGGAATTCCC) have been prepared in which the nucleosides are sequentially replaced by (t)-butan-l,3-diol to give oligodeoxyrlbonucleotides that lack the deoxyrlbose moiety at the chosen position. The diol unit was converted into the phosphoramidite derivative... 

Aliphatic azo compounds may be obtained on anodic oxidation of A,A -dialkylhy-drazines amines or their derivatives may be oxidized to azo compounds in some cases. Anodic oxidation at a graphite electrode of rerf-butylamine containing some aqueous sodium perchlorate thus yields 2,2 -azoisobutane together with some azoxy-te Y-butane and minor amounts of nitro-fe/t-butane [83].

As mentioned earlier, the stationary phase must also be rendered nonextractable under supercritical fluid conditions. This has been accomplished by in situ free-radical crosslinking. Excellent results have been obtained using azo-t-butane as free-radical generator ( ). Azo-t-butane is superior to peroxides because its decomposition products are nonpolar (nitrogen gas and t-butane), and it does not promote oxidation of susceptible stationary phases with consequent activity and deterioration ( ). Other azo compounds are currently under investigation as well. Using azo-t-butane, both apolar and polar nonextractable phases have been produced for small-bore columns.

Certainly the most promising application of MFI membranes is in hydrocarbon separations. Adsorption increases with the carbon number for linear compounds and steric effect allows to separate /2-butane from t-butane. Consequently at low temperature the permeance decreases when the carbon number increases and at high temperature, differences in diffusion factors... 

However, the potential range within which the spin trap is electro-inactive is considerably reduced. This, the commonly used trap nitroso-t.-butane is reduced at a potential -0.98 V (vs. Ag/AgI) at mercury in dimethyl-formamide. The range may be extended by substitution of appropriate aryl groups for butane [114]. Nitroso compounds also present a problem in that some compounds have been shown to undergo a monomer/dimer equilibrium in solution in which only the monomeric form acts as a radical trap. Hence, for nitroso compounds, it is necessary to understand this equilibrium, as well as the electrochemical properties of the trap, before it may be used in the investigation of electrode reactions.

Two or more compounds with the same molecular formula but different properties are called isomers. Isomers with different arrangements of bonded atoms are constitutional (or structural) isomers alkanes with the same number of C atoms but different skeletons are examples. The smallest alkane to exhibit constitutional isomerism has four C atoms two different compounds have the formula C4H10, as shown in Table 15.3 on the next page. The unbranched one is butane (common name, /t-butane n- stands for normal, or having a straight chain), and the other is 2-methylpropane (common name, i obutane). Similarly, three compounds...
