摘要：
一种有机化合的制备方法，具体是指1－(2，6，6－三甲基环己－3－烯基)丁－2－烯－1－酮的制备方法，它是通过一种以1－乙酰基－2，6，6－三甲基环己－3－烯为原料，经格氏试剂处理后和乙醛缩合、脱水制备1－(2，6，6－三甲基环己－3－烯基)丁－2－烯－1－酮的方法。本发明的优点是简化了操作，还有成本低、产率高、三废少等特点，产品香气符合要求。本发明的产品具有较强的花香香气和良好的扩散力，阈值较低，它少量加入香精中可以起到显著提升玫瑰香气的作用。
摘要（英）：

The invention relates to a preparation method of an organic compound, in particular to the preparation method of 1-(2, 6, 6-trimethyl hexanaphthene-3-alkylene) butyl-2-alkene-1-ketone. The method is that the 1-(2, 6, 6-trimethyl hexanaphthene-3-alkylene) butyl-2-alkene-1-ketone is prepared by adopting 1-acetyl-2, 6, 6-trimethyl hexanaphthene-3-alkene as raw material to be condensed and dehydrated with aldehyde after the treatment of Grignard reagent. The invention has the advantages of simple operation, low cost, high productivity and little three wastes, etc., while the incense of the product which is prepared by the invention is up to the standard. The product of the invention has stronger flowery odour incense, excellent dispersion and low threshold value, and the invention can be slightly added into essence so as to greatly upgrade the incense of rose.
