GirhotolAmine Process. This process developed by the Girdler Corporation is similar in operation to the alkali carbonate processes. However, it uses aqueous solutions of an ethanolamine, ie, either mono-, di-, or triethanolamine. The operation of the Girbotol process depends on the reversible nature of the reaction of CO2 with monoetbanolamine [141-43-5] to form monoethanolamine carbonate [21829-52-7].

JR,9Z)-9-Octadecen-4-olide (30) is the female pheromone of the currant stem girdler (currant sawfly, Janus integer). Both the enantiomers of 30 were synthesized as summarized in Scheme 44 [69]. Lipase-catalyzed asymmetric acetylation of ( )-A was the key-step to give unreacted CR)-A and acetylated (S)-B. 

Volatiles and cuticular extracts from both sexes of the currant stem girdler, Janus integer, were analyzed by GC-EAD using antenna ofboth sexes. A female specific compound, (9Z)-octadec-9-en-4-olide 7, was identified as active only on male antennas [33]. Separation by chiral GC has shown that only one enantiomer is produced in females. The synthesis ofboth enantiomers has recently been described [34] and the field testing results are forthcoming. 

We report here about the investigation of the low temperature watergas shift reaction on an industrial catalyst (GIRDLER G 66-B and E with copper and zinc oxides as main components) under transient conditions by means of wavefront analysis. After a qualitative analysis to obtain information about the relevant mechanistic scheme the main effort has been concentrated on the dependence of the microkinetics on different oxidation states of the catalyst. The watergas shift reaction in its overall formulation...

A lactone, (2 )-9-octadecen-4-olide, has been identified as a female specific antennally active compound from the currant stem girdler, Janus integer Norton (Hymenoptera Cephidae). Comparison of the y-lactone and a synthesized racemic mixture of (2 )-9-octadecen-4-olide on a chiral GC column showed the presence of a single component in the natural material. ...
