Project Report on Alcohol From Potato

The name alcohol (RH70) refers to only a few substance, The ethyl  alcohol   found  in  intoxicating  beverages,  the iso propyl alcohol  found  in  the medicine cabinet, and  the  wood  alcohol (methanol) used as a solvent for shellac. The tenth of the matter is  that  the  alcohol  are a  very  large  class  of  compounds, exhibiting  a rich and diverse chemical behavior. A wide  variety of  naturally occurring alcohols have been identified, from  both plant and animal sources. The fermentation of sugar and starch by yeast  or  bacteria  is an important source  of  ethanol  and  1-butanol.  However,  many alcohol that are not  found in natural source,  or are present only in small amounts can be prepared by transformation  of  other  functional groups.  Examples  of  such syntheses  include  the  hydrolysis  of  alkyl  halides. Starch (C6H10O5)  n.  The  principle reserve poly sachaid in plants  constitutes  substantial  portion of the human diet. It   is  the principal  component  of most seeds, tubers, and  roots and is produced  commercially  from corn, wheat, rice,  tapicca  Potato, Sago  and other sources. Starch is a mixture of linear (amylose)   and   branches  (amylopection)  Polymers  of  alpha-D glucopyranosy  units. Natural  starch occurs usually as  granules composed of  both linear and branched starch molecules.  However, some  starches   are composed  only  of  branched  molecules and there  are  termed  waxy starches because of the vitreous  sheets of a cut seed surface.
