APPLICATIONS

Polymerization is initiated generally by free radical. There are four types of free radical initiators which initiate polymerization.
  • Peroxides including hydroperoxides (tertiary-butyl hydroperoxide, benzoylperoxide)
  • Azocompound thermal initiators (azoisobutyronitrile)
  • Redoxinitiators (mixture of iron(III) acetylacetonate): free radicals are formed by one-electron transferreactions. Useful in low temperature and emulsion polymerization
  • Photoinitiators (benzoin, benzil dimethylketal)

The main advantage of polymerization started by photoinitiators is temperature-independence and easy control. It can be conducted at very low temperatures and can be stopped simply by removing the light source. Photoinitiators are compounds that break down into free radicals upon exposure to ultraviolet radiation. Photoinitiators undergo a unimolecular bond cleavage upon irradiation to yield free radicals (benzoin esters; benzil ketals; alpha-dialkoxy acetophenones; alpha-hydroxy-alkylphenones; alpha-amino alkyl- phosphine; acylphosphine oxides). Another type of photoinitiators undergo a bimolecular reaction where the excited state of the photoinitiator interacts with a second molecule (a coinitiator) to generate free radicals(benzo phenones,amines; thioxanthones,amines; titanocenes). Photoinitiators are widely applied in UV curing inks, wood coatings, paper coatings, optical fiber, PCB, screen printing , paper varnish and other surface coatings.

OTHER INFORMATION
Morpholine is a hygroscopic, weak basic, oily and  volatile liquid; with a characteristic amine odor; melting point -5 C,  boiling point at 129 C; miscible with water and with many alcohol organic solvents such methanol, ethanol, acetone, ethers, BTX (it is used as a solvent itself), but has limited solubility in alkaline solutions. It decomposes on heating resulting toxic nitrogen oxides and violently reacts with strong oxidants resulting fire hazard and attacking copper and its compounds. It can be prepared by the reductive ammonation of diethylene glycol with hydrogen, by the dehydration of diethanolamine with a strong acid (oleum) and by heating bis(chloroethyl)ether with excess ammonia. It is a cyclic amino ether as well as a secondary amine. 1,4-Dioxane is the form which nitrogen atom is replaced by oxygen. The ether property of morpholine is typically inert. The secondary amine property involves in the most chemical reactions. Morpholine is a versatile chemical. It is used as a solvent itself for resins, dyes, and waxes. Its alkyl derivatives (e.g. N-methylmorpholine, N-ethylmorpholine) are used as a catalyst for the production of polyurethane foams. Nitrogen in ring system involves in the introduction of sterically demanding asymmetric center to achieve effective stereocontrol. Morpholine has a similar volatility with water. It is used as a pH adjustment additive in fossil fuel and steam systems as a corrosion inhibitor. The most important use is as a chemical intermediate to prepare below compounds:
  • Rubber chemicals for vulcanization and stabilization
  • Corrosion inhibitors in boiler water treatment system and in aqueous hydraulic liquids to protect metals against corrosion and tarnish by acid fumes.
  • Optical brighteners which are stable to chlorine bleaches for the use in detergent formulations
  • Fatty acid salts for the formulation of water-resistant emulsifier or plasticizer in toiletry and cosmetic products.
  • Sulfonamide bactericides or disinfectants
  • Quaternary morpholinium salts for hair conditioners and deodorant products
  • Colourants for hair dyes and blueprints
  • Pharmaceuticals (analgesics, local anaesthetics, antibiotics, antimycotics and for anti-plaques)
