Embodiment 1

[0015] For waste oil containing 10% palmitic acid, 10% octadecanoic acid, 40% oleic acid and 15% linoleic acid, after filtering out impurities, proceed according to the following steps and methods:

[0016] (1) Add 3 parts of 10% H 2 SO 4 Solution, after stirring for 30 minutes, washed with water twice;

[0017] (2) Stand still for 10 hours, take the upper organic phase;

[0018] (3) Add 1 part of Tween-80 to 20 parts of organic phase and stir for 1 hour to obtain scheelite collector.

[0019] The scheelite collector prepared in this example is a light yellow to brownish red liquid, soluble in water at a temperature ≥ 10°C, and the aqueous solution is a transparent light yellow solution with a water solubility of 3%. Its infrared spectrum is shown in figure 1 Shown, the absorption peak (cm -1 ): 3430.7, 3104.2, 2923.6, 2856.1, 2100.1, 1641.1, 1558.2, 1427.1, 1106.9, 1039.4, 918.

Embodiment 2

[0021] For waste oil containing 40% palmitic acid, 5% octadecanoic acid, 10% oleic acid and 30% linoleic acid, first filter out impurities, and then proceed according to the following steps and methods:

[0022] (1) Add 1 part of 30% H 2 SO 4 Solution, after stirring for 30 minutes, washed with water 3 times;

[0023] (2) Stand still for 5 hours, take the upper organic phase;

[0024] (3) Add 2 parts of TX-10 to 20 parts of organic phase and stir for 0.8 hours to obtain scheelite collector.

[0025] The scheelite collector prepared in this example is a light yellow to brownish red liquid, soluble in water at a temperature ≥ 10°C, and the aqueous solution is a transparent light yellow solution with a water solubility of 5%.

Embodiment 3

[0027] For waste oil containing 30% palmitic acid, 7% octadecanoic acid, 35% oleic acid and 10% linoleic acid, first filter out impurities, and then proceed according to the following steps and methods:

[0028] (1) Add 2 parts of 20% H 2 SO 4 Solution, after stirring for 30 minutes, washed with water 3 times;

[0029] (2) Stand still for 20 hours, take the upper organic phase;

[0030] (3) Add 3 parts of Tween-80 to 20 parts of organic phase and stir for 0.5 hours to obtain scheelite collector.

[0031] The scheelite collector prepared in this example is a light yellow to brownish red liquid, soluble in water at a temperature ≥ 10°C, and the aqueous solution is a transparent light yellow solution with a water solubility of 6%.

Abstract

The invention discloses a scheelite collecting agent and a preparation method and application thereof. The scheelite collecting agent is prepared from gutter oil, the scheelite collecting agent can beprepared by the following method including the steps that after impurities in the gutter oil are filtered out, 10 parts of the gutter oil are taken out, 1-3 parts of 10-30% H2SO4 solutions are added,and after stirring is carried out for 30 minutes, washing with water is carried out for 2-3 times; still standing is carried out for 5-20 hours, and upper organic phase is taken out; and 1-3 parts oftween-80 or TX-10 are added to 20 parts of the upper organic phase, stirring is carried out for 0.5-1 hour, and the scheelite collecting agent is obtained. The scheelite collecting agent is simple inprocess, easy to operate and high in practicability, harmless utilization of the gutter oil can be achieved, and the pharmaceutical production cost can be reduced effectively. The preparation methodof the scheelite collecting agent is applied to gutter oil containing 10-40% of palmitic acid, 5-10% of octadecanoic acid, 10-40% of oleic acid and 10-30% of linoleic acid.

Description

technical field [0001] The invention relates to the technical field of waste recycling, in particular to a waste oil scheelite collector and a preparation method and application thereof. Background technique [0002] Scheelite collectors are mostly anion collectors, and the most commonly used anion collectors are fatty acid agents. Commonly used scheelite collectors are fatty acid agents such as oleic acid soap, oxidized paraffin soap, and tar soap. The selective collection effect is poor and the price of the agent is high. In order to improve its selective collection ability, scientific research work It has been modified and compounded by researchers for a long time. At the same time, using low-cost raw materials to develop scheelite collectors is one of the current research directions for beneficiation agents. [0003] Waste oil generally refers to all kinds of low-quality oils that exist in daily life, such as recycled food oil and repeatedly used frying oil, which have...
