Embodiment 1

[0019] Put the original kapok fiber in the reactor, when the ratio of kapok fiber: ethanol is 1:50, add acetic anhydride with ethanol mass fraction of 15%, react at 80°C for 2h, separate the product, wash twice with ethanol, and Dry at 80°C to constant weight to get kapok fiber oil absorbent. The product in the present embodiment absorbs chloroform 75g / g, absorbs toluene 45g / g, absorbs normal hexane 42g / g.

Embodiment 2

[0021] The raw kapok fiber was placed in a reactor, treated with hydrochloric acid with a mass fraction of kapok fiber of 0.3% at 60° C. for 1 h, and then the product was isolated. Dry the isolated product and place it in a reactor. When the ratio of kapok fiber: ethanol is 1:50, add acetic anhydride with an ethanol mass fraction of 15%, react at 80°C for 2 hours, isolate the product, and wash it twice with ethanol , and dried at 80°C to constant weight to obtain kapok fiber oil-absorbing agent. The product in the present embodiment absorbs chloroform 83g / g, absorbs toluene 48g / g, absorbs normal hexane 45g / g.

Embodiment 3

[0023] Put the original kapok fiber in the reactor, when the ratio of kapok fiber: isopropanol is 1:75, add butyric anhydride with isopropanol mass fraction of 25%, react at 100°C for 1h and isolate the product, and use isopropanol Wash twice with alcohol, and dry at 80°C until constant weight to obtain kapok fiber oil-absorbing agent. The product in the present embodiment absorbs chloroform 78g / g, absorbs toluene 46g / g, absorbs normal hexane 42g / g.

Abstract

The invention discloses a kapok fiber oil absorption material. The kapok fiber oil absorption material is obtained by performinh acylation treatment on the kapok fiber, filtering, washing and drying the treated kapok fiber. The kapok fiber has wide source and low cost. The oil absorption material prepared by the kapok fiber has an oil absorption capacity reaching 40-80 times, and can reach oil absorption balance in 30 minutes. The kapok fiber oil absorption material can still float on water surface after oil absorption, so that the kapok fiber oil absorption material can be used for large-scale treatment of oil pollutions in sea surfaces and water surfaces of rivers and lakes.

Description

technical field [0001] The invention relates to a kapok fiber oil-absorbing material. Background technique [0002] In recent years, in the process of oil extraction, refining, transportation, transfer and use of oil products, crude oil and refined oil leakage incidents have occurred frequently, and the pollution to the water environment has become more and more serious. The development of high-efficiency oil-absorbing materials has always been a concern of people. hotspot. Oil-absorbing materials can generally be divided into inorganic materials, organic synthetic materials and natural polymer materials. Inorganic materials such as activated carbon, expanded graphite, peat, silica, organically modified clay, etc., have been seldom used because of their low oil absorption rate and difficulty in recycling after oil absorption; organic synthetic materials include polypropylene, polyurethane foam, acrylate They have good lipophilicity and oil-absorbing efficiency, but their e...
