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...

Problems solved by technology

Processing these three kinds of rosin raw materials all can not reach desired effect by common artificial rosin processing method: 1, artificial rosin is in heating and dissolving process, usually adds the turpentine oil that accounts for raw material weight 15%~25% and makes solvent dissolution rosin, and this Due to the severe oxidation of the three raw materials, a small amount of turpentine can no longer dissolve or dilute the oxides. After being heated, the oxidized resin becomes an extremely viscous black jelly. This jelly has a large specificity and settles at the bottom of the equipment. , when produced by the dripping method, it will affect the heat conduction, causing the consequences of burning through the bottom of the pot, and in severe cases, it will cause damage and loss to life and property

Production by the steam method will stick the sieve plate of the equipment, block the pipeline, and easily lead to safety accidents

2. Oxidized turpentine turns into jelly after being heated. Due to the poor air permeability of this jelly, it adheres to bark impurities and sediment when it dissolves, and cannot be easily separated from impurities. The filter residue contains many active ingredients and is discarded. , the product yield is extremely low

3. The clarified slag (middle layer fat liquid) in steam rosin production is a kind of suspended matter, the specific gravity is between water and fat liquid, and it is difficult to separate the suspended matter by usual clarification methods

4. Process the middle layer of fat liquid by simple heating, the product has no quality index at all, the recovery rate of rosin and turpentine is extremely low, and processing and filtering is very difficult and dangerous
