Discovery Of Bakelite 2
Bakelite was maven of the first artificial plastics observed. Chemist, Leo Baekeland dveloped
this plastic in 1907 as he set out to find the replacement of shellackk; lac rosin melted into thin flakes for
making varnish. Shellac at the time was a natural and therefore an expensive product.There would be a
wide market for any reasonably priced substitute. Baekelands research scheme, begun in 1905, focused
on finding a solvent that could dissolve the resinou. Finding a substitute for shellac wasnt such an easy
task, it took try after try to intention it out. Attempt after attempt Baekeland finally discovered a way to
dissolve the gummy residue which was nearly unimaginable to remove from glassware. Instead of trying
to develop a resin tha would be impervious to any slovent like planned, he discovered that phenol
and formaldehyde could be made into a thermoset solid that didnt burn, boil, melt, or dissolve
even in acid.

Baekelands experiments involved the manipulation of phenolformadehyde reactions through
little control of the temperature and pressure at which reactions were performed. Much of these
experiments were performed in a 1.5 meter-tall reactor vessel, he called Bakelizer. ( Roger Smith
( 2001). This experiment proved that the existent fuck be dyed of any color and can go through the
manufacturing process without any effects on the physical properties of the solid.

The announcement to his discovery took place at the annual meeting of the American Chemical
Society on February 15, 1909. Thanks to Baekelands dicscovery, Bakelitess drawbacks its dark color
and inability to be reshaped prompted research that rapidly led to the discovery of several new families...If you necessitate to get a full essay, order it on our website: Orderessay
