A synthesis process of cetirizine hydrochloride

A new technology for synthesizing cetirizine hydrochloride. The technology includes following steps: oxidizing hydroxyzine, which is used as a raw material, into a substance containing an aldehyde group; further oxidizing the substance containing the aldehyde group into cetirizine; and finally performing a salification and purification process to obtain the cetirizine hydrochloride. A total yield of the synthetic method is higher than 80%. Meanwhile, the method is simple in operation, is short in production period, is low in energy consumption and cost, is little in waste water, waste gas and residues and is suitable for large-scale industrial production.
