Octa-iso-pentyloxyphthalocyanine lead with high solubility was designed and synthesized to choose good characteristic phthalocyanine gas sensing material.

Phasetransfer catalysis Willianson ether method was used instead of the traditional Willianson ether method to synthesize isoamyloxyacetic acid from isoamylalcohol and chloroacetice acid, which overcame the disadvantages of harsh and dangerous reaction condition, low yield, high impurities content etc.

A novel process for synthesis of flavor allyl cyclohexoxyacetate and allyl amyl glycolate;
