Embodiment 1
[0027] A kind of preparation method of rosin and turpentine, concrete steps are as follows:
[0028] (1) Cleaning the rosin with a cleaning solution, wherein the cleaning solution is a mixture of dimethylacetamide and hot water with a weight ratio of 1:10, wherein the temperature of the hot water is 60-70°C;
[0029] (2) dissolving: the rosin is transported into the dissolving pot, and at the bottom of the dissolving pot, it is heated by water vapor at a temperature of 90-100° C. to make the rosin dissolve in the dissolving solution in the dissolving pot, wherein the added weight of the dissolving solution is as described 40% of the turpentine weight, the dissolving solution is made up of the following components by weight: 10 parts of water, 20 parts of dimethylacetamide, 10 parts of turpentine and 0.1 part of oxalic acid;
[0030] (3) Water washing: add the dissolved fat liquid into hot water at a temperature of 80-90°C for washing, so as to wash off the dimethylacetamide, p...

Abstract
The invention discloses a preparation method of colophony and turpentine, and belongs to the technical field of the processing of rosin. The method comprises the following steps: (1) dissolving: conveying rosin into a dissolving pan, introducing water vapor at the bottom of the dissolving pan, and heating rosin; (2) water cleaning: adding dissolved rosin liquid into hot water, and cleaning the dissolved rosin liquid; (3) clarification: putting the rosin liquid of the dissolved rosin in a high pan, making the rosin liquid stay for a period of time, putting the rosin liquid of an upper layer in the high pan into a clarifying pan, and carrying out clarification; (4) distillation: putting the clarified rosin liquid into a preheating rosin storage pan, carrying out preheating, then putting the preheated rosin liquid into a continuous distilling pan, and carrying out distillation to finally obtain colophony and turpentine. According to the preparation method of rosin and turpentine, dimethyl acetamide is added into dissolving liquid as an organic solvent for dissolving rosin; the dissolution of rosin is further promoted; a dissolution time of the blocky rosin is shortened. Meanwhile, rosin is also cleaned with cleaning liquid before being dissolved; the surface of rosin are cleaned cleanly, and then subsequent dissolution and purification steps are carried out; the quality of colophony and turpentine is improved.
Description
【Technical field】 [0001] The invention relates to the technical field of rosin production, in particular to a preparation method of rosin and turpentine. 【Background technique】 [0002] Pine resin is a solid resin acid, that is, a mixed solution formed by dissolving rosin in turpentine. Pine resin is a resin secreted by pine tree trunks, which belongs to the product of tree physiological activities, and is viscous or massive solid in the air. Rosin is rich in rosin and turpentine. Rosin and turpentine are widely used chemical basic raw materials. Among them, rosin has anti-corrosion, insulation, adhesion, softening and other properties. It is a synthetic rubber, paint, soap, emulsifier, paper, etc. The main raw and auxiliary materials of various chemical products. Turpentine is a colorless or light yellow volatile oil, widely used in paint, leather and other industries. Therefore rosin must be processed to separate the rosin and turpentine contained in the turpentine to p...
