Neutral oxygen compounds (NOC) are the largest and most typical group of compounds of Estonian shale resin, but in view of their complex composition and lack of reliable methods of analysis very little is yet known about them. The author has characteristics of NOC which boil under 300C. Below we give some data on the individual composition of NOC which boil under 200C. This group of NOC is also present in the raw material used in the production of synthetic detergents, which necessitates additional methods and equipment in the technological system. In connection with this, study of the composition of NOC of this fraction of resin is of interest from the point of view of both improving the quality of synthetic detergents and revealing the composition of these NOC as a new specific raw material for the chemical industry.
