  cation equivalent
α-Heterocyclic α-aminoesters were obtained in good yields by reaction of a glycine cation equivalent and different heterocyclic nucleophiles; diastereoselectivity using a carbohydrate (galactopyranose) as N-protecting group was modest.

The inhibitory functions of inorganic salts (KCI,NaCL and CaCl_2) ,single or inbinary mixture,to the stale samples taken from Dagang Oil Fields are studied bycapillary suction time (CST),dilatancy,and rolling tests. It is shown that the inhibitory capacity of single cations is arranged in an order which is depondentupon the equivaient concentration of the cationratio;the inhibition-cation concentration retationship for Ca ̄(2+) is different from that for K ̄+ and Na ̄+; some binary mixtures of proper cation and...

采用CST和膨胀试验方法研究了单种无机盐和二元混合无机盐对大港油田泥页岩的抑制作用。结果表明,K ̄+、Na ̄+和Ca ̄(2+)抑制泥页岩分散的能力大小顺序与离子当量浓度有关,Ca(2+)的抑制作用随浓度变化的规律与K ̄+、Na ̄+的不同。对某一泥页岩,恒定当量浓度的二元混合盐溶液在离子配比合理时,其抑制能力强于(至少等同于)单种无机盐。
