9758. BarbÚ, P. A., Garelli, F., and Paoli, G. de. May 5. Fatty acids; glycerine.-Fats are saponified by emulsionizing them with 0À5 per cent of ammonia and treating with steam at 130-160‹ C. and 3-6 atmospheres for about 8 hours. The glycerine water is run off from the insoluble fatty acids. The apparatus comprises a helical stirrer 3, a steam coil 5, and a steam injector 4. Specifications No. 4733, A.D. 1882, and No. 12,210, A.D. 1907, are referred to. to.
