| titleOfInvention | Process for producing concentrate containing 1-triacontanol or 1-triacontanone from leaves of medicago sativa l. |
| abstract | 1-triacontanol or concentrates contg. 1-triacontanol are prepd. from the leaves of lucerne (medicago sativa) by extn. of the wet or dry ground vegetable matter with solvents which are not good solvents for 1-triacontanol, like alkanols with 1-3 carbons, pref. methanol at 0-10 deg.C.. The soaked vegetable matter is now repeatedly extd. with boiling chloroform, benzene, chlorobenzene, xylene, THF or pyridine, the resulting organic phase is concentrated, the concentrate dissolved in boiling acetone and left to stand at a temp. around zero deg.C. for pptn. to occur. The ppte. is sepd. by centrifugation. - (a) The fraction contg. 10-20 wr.% 1-triacontanol is added to boiling acetonitrile. At a temp. in excess of 50 deg.C. 1-triacontanol goes into soln., while the waxy impurities form a separate molten phase. In this way a concentrate contg. at least 70 wt.% 1-triacontanol is obtd.. (b) A 98 wt.% pure end prod. cna be prepd. by recrystallisation from chloroform, hexane, cyclo-hexane or benzene. |
