Method for producing colophony by using natural turpentine and residue and waste liquor from colophony production factory

Abstract

The invention discloses an abietyl producing method through natual colophony and abietyl factory waste liquid, which is comprises the following steps: dissolving; filtering roughly; stewing; clearing; filtering distilled waste; distilling the filtrate; packaging the product. The invention increases the usage of dissolved oil (abies) greatly based on common abietyl manufacturing technology, which quickens the impurity separation goal.

Description

technical field

[0001] The invention relates to a method for producing rosin, in particular to a method for producing rosin by using natural rosin and residue waste liquid in rosin production. Background technique

[0002] Pine resin is a mixture of resinous acid and turpentine, and it is a colorless and transparent viscous liquid when it first flows out from the tree body. At present, it is obtained by artificially collecting turpentine, and then processed into rosin and turpentine, which become important chemical raw materials. There are two kinds of processing methods for artificially collected rosin: steam method and drip method. The steam method uses the water vapor produced by the steam boiler as the heat source. First, the pine resin is heated and dissolved, and the large impurities are filtered out, and then the fine impurities and most of the water are further removed by a clarification method. Finally, the purified liquid is distilled The turpentine is steamed wi...
