| titleOfInvention | A kind of preparation method of chromatographic grade n-decane |
| abstract | The invention provides a kind of preparation method of chromatographic grade n-decane, specific preparation process is as follows：(1) under the conditions of ice-water bath, to n-decane is added in there-necked flask, 10-25 DEG C of keeping temperature adds 105% sulfuric acid under stirring, the wherein volume ratio of n-decane and 105% sulfuric acid is 1000:40, continue to stir 1 hour, point liquid removes sulfuric acid layer；(2) oil reservoir is cleaned using 10% NaOH, wherein, 10% NaOH is 1 with the volume ratio of oil reservoir：2, the oil reservoir after washing adds drier, and drier consumption is the 5% of oil reservoir weight, is dehydrated aftercut, intercepts boiling point fraction, is obtained final product；, using industrial n-decane and low concentration oleum low-temperature sulfonation preparative chromatography n-decane, rationally, product purity is high for process is simple, the need for being adapted to scale industrial production for the preparation method. |
