Pine Oil and Modified Products

Pine oil is the product that is distilled from pine stump or turpentine. Currently pine oil frothers (also called as 2 oil) are the modified products of turpentine. And the main functional component of pine oil frothers is terpenol. The general expression of terpenols is as follows  

The structures and physical properties of various terpenols are as follows

Pine oil frothers can be synthesized by adopting pinene as raw material in the presence of acid as a contact agent. Take a-pinene for example, and the synthetic reaction of 2 oil can be given as follows  

2 oil is characterized by high frothing capability and foam evenly. Pine oil frothers can be used to flotate pencil stone, sulfur, graphite, molybdenite, and coal.
