Sharypov*, Natalia G. Beregovtsova, Sergey V. Baryshnikov and Aleksey V. <...> Rudkovsky Institute of Chemistry and Chemical Technology SB RAS 50-24 Akademgorodok, Krasnoyarsk, 660036, Russia Received 26.03.2015, received in revised form 07.05.2015, accepted 26.06.2015 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 signifi cant amounts of ethyl esters of hydroxy – and oxyacids. <...> All rights reserved * Corresponding author E-mail address: sharypov@icct.ru # 401 # Victor I.
