  木霉菌的脂肪酸去饱和和延伸反应 1‐OH‐2‐3

  摘要：

  木霉菌催化的脂肪酸去饱和和延伸反应。研究了1-OH-2-3。该菌株主要将棕榈酸（16：0）转化为硬脂酸（18：0），然后进一步转化为油酸（c 9-18：1），亚油酸（c 9，c 12-18：2）和α亚麻酸（c 9，c 12，c 15-18：3）通过延伸，分别进行Δ9，Δ12和Δ15去饱和反应。棕榈油酸（Ç 9-16：1）和顺式9，顺式：由应变0 12-十六碳酸也从16产生。该菌株将正十三烷酸（13：0）转化为顺式9-十七碳烯酸和顺式9，顺式12-十七碳二烯酸，分别通过延伸和Δ9和Δ12去饱和反应形成。通过Δ9去饱和作用，菌株使反式-牛痘酸（t 11-18：1）和反式-12-十八烯酸（t 12-18：1）饱和。来自t 11-18：1的产物被鉴定为顺式-9，反式-11十八碳二烯酸和反式9，反式11十八碳十八烯酸的共轭亚油酸（CLA）。来自t 12-18：1的乘积被确定为顺式9，反式十二十八碳二烯酸。顺式-

  A method is provided for preventing copper and zinc from being eluted from a copper-alloy-made plumbing instrument that includes valves and pipe joints and suppresses copper and zinc from being eluted from the copper-alloy-made plumbing instrument while using for the plumbing instrument copper alloy as-is that includes bronze and brass, to provide a copper-alloy-made plumbing instrument using the method and to provide a film-forming agent. The method forms on at least a liquid-contact portion of the copper-alloy-made plumbing instrument a film of an organic substance comprising unsaturated fatty acid and coating with the film both copper and zinc in the surface layer of the liquid-contact portion of the plumbing instrument, thereby suppressing the elution of copper and zinc.

  Wax compositions derived from metathesized natural oils and amines and methods of making wax compositions from metathesized natural oils and amines are provided. The wax compositions comprise amidated metathesized natural oils formed from a metathesized natural oil and at least one amine. The methods comprise providing an amine and providing a metathesized natural oil. The methods further comprise mixing the amine and the metathesized natural oil in the presence of a basic catalyst or heat, causing a reaction between the amine and metathesized natural oil, therein forming the amidated metathesized natural oil.
