Embodiment 1

[0017] Embodiment 1 Get 1000g of processed waste oil and 90g of formic acid and place them in a reactor, feed circulating hot water, slowly add 670g of concentrated sulfuric acid hydrogen peroxide dropwise at about 40°C (hydrogen peroxide: concentrated sulfuric acid=200: 1), drop After the addition, the temperature was rapidly raised to 70°C, and the reaction was carried out at constant temperature for 6 hours. The sample was placed in the still for 2 hours, the lower layer was separated, and the remaining oil layer was washed with 5% sodium bicarbonate solution until slightly alkaline (PH ≈ 8), and then washed with distilled water (PH ≈ 7). Distillation and dehydration under reduced pressure gave a clear and transparent light yellow oily product.

Embodiment 2

[0018] Example 2 Weigh 400g of PVC, 20g of lead salt, 2g of paraffin, 50g of dioctyl phthalate, and 50g of epoxidized waste oil, and mix them uniformly; place the mixed sample at a roller temperature of about 165°C.

Abstract

The invention relates to a formula of epoxy gutter oil plasticized PVC (Poly Vinyl Chloride). In a test, sulfuric acid is taken as a catalyst, hydrogen peroxide is taken as an oxygen supply agent, formic acid is taken as an oxygen receiving agent, and the epoxidation reaction conditions of gutter oil are researched in one step by adopting performic acid. The method is suitable for industrial popularization and application. Therefore, the optimal processing formula of the epoxy gutter oil plasticized PVC is designed by taking the epoxy gutter oil as a plasticizer in the PVC production process instead of the conventional dioctyl phthalate.

Description

technical field [0001] The invention relates to a method for preparing epoxy waste oil by a peroxyformic acid method, so as to be used in the research of plasticized polyvinyl chloride (PVC) formula. Background technique [0002] my country produces at least 3 million tons of waste oil every year, of which less than 1 / 3 is made into biodiesel, and the remaining 2 / 3 is basically returned to the table. Using gutter oil to prepare biodiesel has complicated process, high cost and limited application. It has been determined by medicine that long-term intake of waste oil will cause harm to the human body and cause cancer. It is imminent to turn waste oil into treasure and realize the sustainable recycling of resources. [0003] As the most widely used plasticizer in the PVC industry, phthalates account for about 80% of the entire industry. With the in-depth research on dioctyl phthalate (DOP) plasticizers, the toxic effect of DOP on the human body has gradually become prominent...
