Potassium aluminate, K 2 Al 2 0 4, is obtained in solution by dissolving aluminium hydrate in caustic potash; it is also obtained, as crystals containing three molecules of water, by fusing alumina with potash, exhausting with water, and crystallizing the solution in vacuo.
Iodine in alkaline solution converts pyrrol into iodol (tetra-iodopyrrol), crystallizing in yellowishbrown needles, which decompose on heating.
Though introduced with success from Santo Domingo about the middle of the T 8th century, the sugar industry practically dates from 1796, when Etienne Bore first succeeded in crystallizing and clarifying the syrup. Steam motive power was first introduced on the plantations in 1822.
