Problems solved by technology

[0003] Although tall oil has superior performance, the tall oil on the market now has a large rosin smell, which is relatively pungent, often causing people's discomfort during use, and increasing the peculiar smell of the product. The existing tall oil It contains a lot of sulfur element, which is easy to oxidize and volatilize into harmful gas at high temperature, which greatly reduces the safety of product use and is not conducive to environmental protection. In addition, oxidation, corruption and mold will occur during long-term storage of tall oil, which greatly reduces Extended the shelf life of the product, not conducive to long-term storage

Abstract

The invention discloses environment-friendly odorless tall oil and a preparation process, the formula comprises tall oil, an antioxidant, a preservative and an aromatic, the preparation process comprises the following steps: step 1, pine cooking; step 2, solid-liquid separation; step 3, evaporation and concentration; step 4, acidizing treatment; step 5, product separation; step 6, heating adsorption; step 7, negative pressure distillation; step 8, weighing the raw materials; and step 9, mixing and preparing. The preservative and the antioxidant are added, so that the corrosion resistance and the oxidation resistance of the tall oil are improved, the rotting and deterioration probability of the tall oil is reduced, the crude tall oil is heated and adsorbed by the activated carbon, the peculiar smell of the tall oil is reduced, meanwhile, the peppermint oil and the osmanthus fragrans oil are added as aromatics, and enhancement of the aroma of tall oil is facilitated. And through activated carbon adsorption and negative pressure distillation, the content of the sulfur element in the tall oil is effectively reduced, and volatilization of harmful gas is avoided.

Description

technical field [0001] The invention relates to the technical field of tall oil production, in particular to an environmentally friendly and odorless tall oil and a preparation process thereof. Background technique [0002] Tall oil, also known as tall oil, is a by-product recovered from pulp waste liquid in pulp mills with pine wood as raw material. The range is very wide. It is used in emulsions and microemulsions in metalworking fluids. As an auxiliary emulsifier, it can reduce the amount of main emulsifier. Compared with commonly used oleic acid, it has faster emulsification speed, superior lubricity, good cleaning effect and effective Certain anti-foaming effect, wide adaptability to hard water, good rancidity resistance. [0003] Although tall oil has superior performance, the tall oil on the market now has a large rosin smell, which is relatively pungent, often causing people's discomfort during use, and increasing the peculiar smell of the product. The existing tall...
