Embodiment 1

[0015] The method that this utilizes natural pine resin to produce rosin comprises the following steps:

[0016] A. Put 30kg of raw material natural rosin into a melting pot, add 3kg of xylene, 1kg of turpentine, 0.1kg of oxalic acid and 8kg of water under stirring conditions, and stir at 60°C to completely melt the raw material of natural rosin. In the process, the generated steam is recycled;

[0017] B. After step A, remove the filter residue by filtering to obtain the first fat liquid and put it into the clarification pot, clarify and separate to obtain the second fat liquid, and then put the second fat liquid into the clarification pot for clarification again , separation to obtain the third fat liquid;

[0018] C. After step B, put the third fat liquid into a still, distill at 150°C for 3 hours, recover the solvent, and obtain the residual liquid as a rosin product.

[0019] The rosin productive rate that present embodiment makes is 81%, and purity is 86%.

Embodiment 2

[0021] The method that this utilizes natural pine resin to produce rosin comprises the following steps:

[0022] A. Put 45kg of raw material natural pine resin into the melting pot, add 5kg of xylene, 3kg of turpentine, 0.3kg of oxalic acid and 12kg of water under stirring conditions, and stir at 80°C to completely melt the raw material natural pine resin. In the process, the generated steam is recycled;

[0023] B. After step A, remove the filter residue by filtering to obtain the first fat liquid and put it into the clarification pot, clarify and separate to obtain the second fat liquid, and then put the second fat liquid into the clarification pot for clarification again , separation to obtain the third fat liquid;

[0024] C. After step B, put the third fat liquid into the still, distill at 180°C for 1 hour, recover the solvent, and obtain the residual still liquid as the rosin product.

[0025] The rosin productive rate that present embodiment makes is 80%, and purit...

Embodiment 3

[0027] The method that this utilizes natural pine resin to produce rosin comprises the following steps:

[0028] A. Put 40kg of raw material natural pine resin into the melting pot, add 4kg of xylene, 2kg of turpentine, 0.2kg of oxalic acid and 10kg of water under stirring conditions, and stir at 70°C to completely melt the raw material natural pine resin. In the process, the generated steam is recycled;

[0029] B. After step A, remove the filter residue by filtering to obtain the first fat liquid and put it into the clarification pot, clarify and separate to obtain the second fat liquid, and then put the second fat liquid into the clarification pot for clarification again , separation to obtain the third fat liquid;

[0030] C. After step B, put the third fat liquid into the still, distill at 160°C for 2 hours, recover the solvent, and obtain the residual still liquid as the rosin product.

[0031] The rosin productive rate that present embodiment makes is 82%, and puri...

Abstract

The invention discloses a method for producing rosin by using naturally fallen turpentine, and belongs to the technical filed of deep processing of rosin. The method comprises the following steps: putting a raw material naturally fallen turpentine in a reaction kettle, adding xylene, turpentine, oxalic acid and water, stirring to completely dissolve the raw material naturally fallen turpentine, filtering to remove filter residues, putting the obtained filtrate in a clarifying pot, clarifying, separating, putting the above obtained fat liquor in a distillation kettle, and distilling to obtain a residual kettle liquid which is the rosin product. The yield and the purity of the rosin product prepared in the invention are above 80% and above 85% respectively.

Description

technical field [0001] The invention belongs to the technical field of rosin production, and in particular relates to a method for producing rosin by using natural ground rosin. Background technique [0002] Pine resin is a kind of natural resin, which is a physiological metabolite produced during the life activities of pine trees. It is a kind of oil-containing natural resin and is a colorless, transparent viscous liquid. Pine resin mainly gathers in the pine resin channel of pine trees, has the aroma and bitter taste of pine trees, and its main components are resin acids, fatty acids, and unsaponifiable substances. After the rosin is processed, the non-volatile terpene solid product obtained is rosin. [0003] Among them, the pine tree species will be damaged by diseases and insect pests, the xylem will be damaged, and a lot of rosin will flow out of the wound, and these rosin will accumulate over time and gather at the roots of the pine tree species. [0004] In the pro...
