A relatively rapid and simple method for the determination of alpha, beta, and gamma cellulose is described. The method ordinarily employs a O.3-g sample, which need not be weighed accurately, but a O.03-g sample also gives fair results. Neither ash nor moisture determinations are involved, in fact, no precision weighings are made. The cellulose is oxidized by potassium dichromate solution, the...
The molecular building block approach was employed effectively to construct a series of novel isoreticular, highly porous and stable, aluminum-based metal-organic frameworks with soc topology. From this platform, three compounds were experimentally isolated and fully characterized: namely, the parent Al-soc-MOF-1 and its naphthalene and anthracene analogues. Al-soc-MOF-1 exhibits outstanding gr...
