以NaNO2与无机酸反应原位生成HNO2为催化剂，对油酸进行顺反异构化。考察了反应时间、温度、搅拌、溶剂、催化剂用量、无机酸种类等因素对反应的影响。确定了在30 min内达到平衡异构化的最佳反应条件，并使副产物的生成量最少。异构化后，含氮的副产物被有效地去除使用柠檬酸。引起顺反异构化的活性物质初步确定为自由基二氧化氮。
Oleic acid wascis-trans isomerized by HNO2 generatedin situ by reacting NaNO2 with a mineral acid. The influence on the reaction of time, temp, agitation, solvent, amt of catalyst and type of mineral acid was investigated. Optimum reaction conditions were defined for achieving equilibrium isomerization in 30 min with minimum by-product formation. After isomerization, nitrogenous by-products were efficiently removed using silicic acid. The active species causingcis-trans isomerization was tentatively identified as free radical nitrogen dioxide.
