Introduction The primary production processes to produce active drugs involves a wide variety of complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat

_______________________________________________________________________________ INTRODUCTION In aqueous solution nickel ion Ni2+ is surrounded by six water molecules which are actually bonded to the central metal ion. This complex is called the hexaquonickel(II) ion. When aqueous nickel chloride is precipitated from solution‚ the nickel ions carry their six water molecules into the crystals and so solid nickel(II) chloride is hydrated‚ has the formula [Ni(H2O)6]Cl2‚ and is more properly called hexaquonickel(II)
