The Volatile Chemicals

As with many drugs in recreational use, there are feds and fashion in inhalants-substances containing volatile chemicals that have psychoactive (and other) effects when inhaled. In the 1960s, the in substance in this category was model airplane glue. More recently a variety of other substances have been sniffed in quest a quick "high," including gasoline, furniture polish, insecticide, transmissin fluid, paint thinners, and more. All are highly toxic and can cause damage to vital organs such as lungs, kidney, liver and brain, and death.

Nitrous Oxide
Recreational use of nitrous oxide, discovered in 1773 and first used in dentistry in the 1849s, actually predates its medical use. Still employed as an anesthetic (it is also the propellant in whipped cream dispensers), among the least toxic inhalants. It is toxic, nevertheless, and death can follow if it is inhaled with insufficient oxygen.

What happens if a person takes nitrous oxide over a long period? Repeated, long-term use can result in nerve damage, muscle weakness, hearing loss, changes in heart rate, impotence, or life threatening anemia due to suppression of bone marrow production (possibly through inactivation of vitamin B12). A leading dental educator even warned in 1981 that dentists and their assistants should beware of long term low level exposure, checking their equipment for leaks and being sure to utilize efficient exhaust system.  A study of 60,000 dental workers, published by the American Dental Association the previous year, had found that people occupationally exposed to nitrous oxide had increased rates in the children of both males and females, and increases in the incidence of certain types of cancers.

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo...

Sulfur

Sulfur or sulphur is a naturally occurring, yellow, water insoluble solid element. Its chemical symbol is S , its atomic number is 16 and its atomic weight is 32.064 sulfur is nonmetal and a member of the oxygen family of elements, which constitutes Group VIA of the periodic table. The discovery of sulfur predates recorded history, and the element has been used since ancient times. The early medical books of Dioscorides of Greece and Pliny the Elder mention sulfur, and fumes from burning sulfur were used in religious ceremonies and for fumigation. Alchemists recognized sulfur as a mineral substance that can be melted and burned. It was first classified as an element by Antonie Lavoisier in 1777. Sulfur Occurrence On earth, sulfur is widely distributed in its elemental state as a secondary mineral or as a volcanic deposit, as well as in combination with a number of metals. Large sedimentary deposits of the almost pure element, mainly of Tertiary age, are found in the coastal r...

Gas Reaction and Solid Reaction

Gas Liquid Reactions When gaseous reactants are absorbed by a liquid, and a chemical reaction takes place , both chemical reaction and mass transfer may control the overall reaction rate. For analysis of this type of system should be consulted. Books by Astarita, Danckwerts, and Sherwood, Pigford, and Wilke should also be helpful. Treatments similar to these references are likewise applicable to the liquid liquid system if chemical reaction is involved in only one of two partially miscible phases and the overall rate is governed by both mass transfer and chemical reaction. Solid State Reactions The solid state reactions refer to decomposition and interaction of solids, and are generally more complex than those of other systems discussed preciously. There have been few systematic analyses of chemical reactions in the solid state. Fairly comprehensive treatments of such reactions are presented in two recent publications by Bamford and Tipper and Schmalzried respectively. Genera...
