Incendiary device naval airship fleet commander Peter Strasser in July 1918, but it was vetoed by Admiral Reinhard Scheer. Incendiary bombs were used extensively in World War II as an effective bombing weapon, often in a conjunction with high-explosive bombs. Probably the most famous incendiary attacks are the bombing of Dresden and the bombing of Tokyo on 10 March 1945. Many different configurations of incendiary bombs and a wide range of filling materials such as isobutyl methacrylate (IM) polymer, napalm, and similar jellied-petroleum formulas were used, many of them developed by the US Chemical Warfare Service. Different methods of delivery, e.g. small
Divinylether fatty acids linoleic acid) and colnelenicacid (from linolenic acid), could be also produced in potato leaves and tomato roots by rearrangement of 9-hydroperoxides. Isomers of colneleic and colnelenic acids were isolated from homogenates of leaves of Clematis vitalba (Ranunculaceae). Similarly, 13-lipoxygenase-generated hydroperoxides serve as precursor of other divinyl ether fatty acids which are produced in bulbs of garlic or Ranunculus leaves. These compounds were named etheroleic and etherolenic acids. Etheroleic acid has systematic name 12-[1′E-hexenyloxy]-9Z,11Z-dodecadienoic acid. Etherolenic acid has systematic name (9Z,11E,1'E,3'Z)-12-(1',3'-Hexadienyloxy)-9,11-dodecadienoic acid. The physiological significance of divinyl ethers is still not fully studied. As infection of potato leaves leads to increased
