摘要：
Methods of ichthyol production from the Israeli shale oil are investigated. Ichthyol (ichthammol) is an anti-inflammation and analgesic remedy, used for curing skin diseases. The scheme developed includes the following steps: purification of the oil fraction; sulfonation of the fraction; neutralization of the sulfonic acids by ammonium hydroxide; purification of the crude ichthyol. The ichthyol yield is 170-250% of the initial fraction (75-120% of the total oil). The ichthyol obtained meets requirements of the British Pharmacopoeia. Simplicity of the synthesis, high yield, and high price for ichthyol make its production economically favourable.
