Lithium perchlorate melting point

The first reported synthesis of acrylonitrile [107-13-1] (qv) and polyacrylonitrile [25014-41-9] (PAN) was in 1894. The polymer received Htde attention for a number of years, until shortly before World War II, because there were no known solvents and the polymer decomposes before reaching its melting point. The first breakthrough in developing solvents for PAN occurred at I. G. Farbenindustrie where fibers made from the polymer were dissolved in aqueous solutions of quaternary ammonium compounds, such as ben2ylpyridinium chloride, or of metal salts, such as lithium bromide, sodium thiocyanate, and aluminum perchlorate. Early interest in acrylonitrile polymers (qv), however, was based primarily on its use in synthetic mbber (see Elastomers, synthetic). 

According to A. Potilitzin, the melting point of trihydrated lithium perchlorate is 95° and, between 98° and 100°, the salt loses approximately two-thirds of its combined water and all the water is lost between 130° and 150° the anhydrous salt melts at 236°, and loses no oxygen at 300° this gas is evolved at about 368°, at 380° the speed of decomposition is rapid—lithium chlorate and chloride are first... 

The technicians have always been well aware of the problems not only in finding a suitable positive electrode, but also in dealing with this available and therefore not-too-precious element. Lithium reacts with humidity, especially with water, and has its melting point at 180°C. Apart from this, the fact that perchlorates and hydrides of hthium are poisonous and must be coped with.
