| titleOfInvention | Abietic acid sulfur ether derivative and preparation method thereof |
| abstract | The invention discloses an abietic acid sulfur ether derivative and a preparation method thereof. The name of the abietic acid sulfur ether derivative is abietic acid methylthio-methyl ester. The preparation method is that the abietic acid methylthio-methyl ester is prepared by directly esterifying common rosin, disproportionated rosin, dehydroabietic acid or hydrogenated rosin and dimethylsulfoxide serving as raw materials in the presence of a catalyst of potassium hydroxide. The abietic acid methylthio-methyl ester can be widely used in the fields such as coatings, printing ink, adhesives, synthetic rubber and the like. The abietic acid sulfur ether derivative has the advantages of: utilization of a new method for generating the abietic acid methylthio-methyl ester by directly performing an reaction on the common rosin, the disproportionated rosin, the dehydroabietic acid or the hydrogenated rosin and the dimethylsulfoxide in the presence of the catalyst of the potassium hydroxide, lower reaction temperature than a common esterification reaction, higher reaction speed, high yield, low product acid value and high stability, so the abietic acid sulfur ether derivative can be used as a plasticizer instead of abietate or applied in the industries such as coatings, printing ink and the like. |
