1) strings of jade patches
2) pelargonic acid
The mixture of oleic acid,water,pelargonic acid and acetic acid was treated with ozone at 0～15℃ before the reaction was fully carried out.
Pelargonic acid has a obvious antifeedant action to the imago of Pissodes punctatus Langor et Zhang.
3) nonene ['nəuni:n]
By technical reform of the process of propylene oligomerization,the quality and yield of nonene are raised,thus the output of nonylphenol grade one is increased,good economic benefit of the unit is obtained.
通过丙烯齐聚工艺的技术改造 ,提高了壬烯的质量和收率 ,从而增加了壬基酚一级品的产量 ,为装置创造了良好的经济效
The effect of various independent variables which affected the selectivity of nonene during the alkylation of benzene and propylene on phosphate catalyst was studied.
A new technology of producing nonene and dodecene by a two-stage reaction temperaturemethod of propene oligomerization over NiSO_4/γ-Al_2O_3 has been developed.
