1) diasteranes
重排甾烷
1.
The GC/MS analyses for alkanes from Late Jurassic source rocks of the Liudong depression,Kailu Basin,northeastern China showed that the concentration of diasteranes in some samples decreases anomalously with depth,suggesting that in this case the formation of these compounds may be not depended on maturity.
陆东凹陷上侏罗统生油岩样品饱和烃色质分析表明,重排甾烷随井深出现含量下降的逆转现象,表明热演化不完全是这类化合物形成的主要控制因素。
2) rearranged drimane
重排补身烷
1.
In these bicyclic sesquiterpanes,the relative abundance of the rearranged drimane is regularly changed in spatial distribution,which may indicate the characteristics of petroleum migration and accumulation in QHD32-6 oilfield.
该油田双环倍半萜中重排补身烷的相对丰度在纵向上和横向上都表现出有规律的变化,这种规律性的变化可能反映了秦皇岛32-6油田油气运移与聚集的特征。
2.
The distributional characters of bicyclic sesquctecpances show that rearranged drimanes are relatively rich in the samples in Region A and relatively poor in Region C, but drimanes are relatively poor in Region A and rich in Region C.
双环倍半萜分布特征显示 ,A区原油重排补身烷含量相对较高 ,C区原油补身烷含量相对较高 ,这一特征与塔里木盆地海相和湖相原油特征相一致 ,暗示南海A、C区原油可能属不同成因类型 ;这一特征与其原油分子组成的非均质性在油区内的变化颇具一致性。
3) alkyl rearrangement
γ-烷基重排
1.
An γ - alkyl rearrangement of an alkyl group in phosphonate is also found during electron impacting.
发现3-取代芳基-2-吲哚基膦酸酯的膦酰基中的烷基在碎裂过程中也产生γ-烷基重排反应,同时讨论了这类化合物的质谱碎裂行为。
4) rearranged hopanes
重排藿烷类
1.
Composition and origin approach of rearranged hopanes in Jurassic oils of cen tral Sichuan basin;
川中侏罗系原油重排藿烷类化合物的组成及成因探讨
5) C30-rearranged Hopane
C30-重排藿烷
1.
According to the characteristics of high C30-rearranged Hopane and extremely low C30 Hopane of the Chang91 source rock,in combination with other geochemical parameters in oil-source correlation,Chang8-Chang9 rese.
以志丹地区长91烃源岩具有异常高的C30-重排藿烷、异常低的C30藿烷这一显著特征为主要依据,结合其他地球化学参数进行的油源对比表明,志丹南部地区的长8—长9储集层原油与长91烃源岩具有密切的亲缘关系,而其他地区长91储集层原油与长91烃源岩的可对比性差。
6) sterane
甾烷
1.
Distribution and sources of steranes and pentacyclic triterpanes in surface soils and bottom sediments from Tianjin;
天津地区表层土壤和河流沉积物中甾烷与五环三萜烷的分布特征及污染源分析

分子式:
CAS号:
性质:酮肟1在酸性催化剂(五氯化磷、三氯氧磷、多聚磷酸、硫酸、乙酰氯、醋酐、氯化氢、氯化亚砜等)的作用下重排为酰胺的重排反应。对称的酮肟重排只得到一种产物;而不对称的酮肟重排,则主要生成与羟基处于反位的R′基重排至氮原子上的产物。式中的R和R′可以是脂肪基或芳香基。为反式酮肟的特征反应,用于确定其构型。
