Claims (2)

1. Способ очистки сульфатного скипидара-сырца от сернистых соединений путем одновременной обработки его водным раствором щелочи и карбонильным соединением и последующей ректификации, отличающийся тем, что в качестве карбонильного соединения используют фурфурол, взятый при объемном соотношении сырье : фурфурол : 5%-ный водный раствор щелочи, равном 1:0,3-1,0:0,1-1,0.1. The method of purification of crude sulfate turpentine from sulfur compounds by simultaneously treating it with an aqueous alkali solution and a carbonyl compound and subsequent rectification, characterized in that furfural is used as the carbonyl compound, taken at a volume ratio of raw material: furfural: 5% aqueous solution alkali equal to 1: 0.3-1.0: 0.1-1.0. 2. Способ очистки сульфатного скипидара по п.1, отличающийся тем, что обработку проводят два и более раза до содержания общей серы в очищенном скипидаре 0,04-0,07 мас.%. 2. The method of purification of sulfate turpentine according to claim 1, characterized in that the treatment is carried out two or more times until the total sulfur content in the purified turpentine is 0.04-0.07 wt.%.
