Their reactive triple bond opens up many possibilities for chemical synthesis. Like insecticides. Our SURFYNOL® surfactants are great defoamers and wetting agents for these and many other products. We're big in perfumery too, where our DIMETHYL OCTANOL is an intermediate in floral scents. Other acetylenic derivatives are used in drugs, food flavorants, soaps, detergents, just about anything you can think of. The charts here will give some idea of the imaginative uses for Airco's family of acetylenics.
