Investigations of upper atmospheric processes are aimed at producing a realistic model of the atmosphere. Of primary importance in producing a model atmosphere is a knowledge of the rate constants of the possible reactions which can occur. Equally important is…

[...] The first section of this thesis describes the studies which led to a satisfactory process for recovering acetic acid. The latter two sections, although of much less importance to large scale manufacture of RDX, contributed to the knowledge of…

There is a region of the upper atmosphere called the mesopause which currently excites much interest. This region lies approximately between the altitudes of 80 and 90 kilometers. Today, knowledge of conditions in this region is necessary to predict satellite…

A knowledge or the individual chemical constituents of bark is important not only from an academic point of view, but is of vital interest to the economy of the wood pulp industry in general. For several years, a major investigation…

The initial objeot of the research was to convert cellulose, a linear polymer, into branched-chain polymere of known constitution by condensing some of its free hydroxyl groups with acetobromoglucose, acetobromocellobiose, or acetobromocellodextrins. A comparison of the linear starting material and…

[...] Within recent years silica gel has received considerable attention because of its use as a sorbent, catalyst and catalyst support. The sorption of about fifty materials on silica has been recorded (2). There is an analogy between gelation of…
