The influence of HCI, Clz, Brz and 1~ on the vapor phase growth of carbon fibers from naphthalene was examined at 1100ยฐC with the expectation of a promotive effect similar to HS. However, these halogen additives were found not to catalyse but to inhibit the growth. Employment of I-chloronaphthalene
## Data are presented on utilizing petroleum asphaltite as an addition to the charge and a binder when obtaining adsorbents as well as the products of their thermal and chemical modification. High effective microporous adsorbents have been produced whose sorption indices are higher than industrial
Changes of composition, structure, and contents of some functional groups, of oils from petroleum binders, in relation to temperature of carbonization from about 710 K to 1200 K have been investigated. Oils from carbonization of petroleum binders are of hydrocarbon type, and their elemental composit
Carbon fibers possess high tensile strengths and are of technological importance as reinforcing agents in composite materials. Considerable effort is being expended to modify the properties of these fibers. Treatment with the halogen fluorides, CIF, or BrF,, at room temperatures results in fibers ha
