The Study of Ethanol Extracts Composition of Organic (Kachkulnya Lake) and Organomineral (Barchin Lake) Sapropels from Novosibirsk Region

The extraction of sapropels of organic type (Kachkulnya Lake) and organo-mineral type (Barchin Lake) from Novosibirsk region by ethanol at a variation of process temperature was studied. It was shown that the rising of the temperature from 50 °C to 200 °C results in an increase the yields of extracts by 19,0 and 13,7 times for sapropels organic and organo-mineral -types respectively The composition of obtained extracts was established by IR and GC – MC methods. Products from sapropel organic type contained 68,1 % ethyl esters, mainly of fatty acids with carbon atoms in the molecule are from 18 to 29 numbers. It was established that relative content of ethyl esters in extract of organo-mineral type sapropel was 43,6 %, they have a signiёcant amounts of ethyl esters of hydroxy – and oxyacids. A distinctive feature of the ethanol extract from organo-mineral type sapropel is the presence of carbohydrates and compounds containing a furan ring.
