Abstract

In saponification and soap base processing of cotton seed oil foot, 0.02-0.3% decolorant comprising hydrogen peroxide solution is added in the second alkalization reaction. The present method not only simplifies the existing production process, but also utilizes the cotton seed oil foot to produce the raw material for making high grade detergent (soap or soap powder).

Description

Cottonseed oil foot decolorant and application thereof
The invention provides a kind of chemical reagent that is used for the decolouring of Oleum Gossypii semen oil foot, in the deep processing of Oleum Gossypii semen oil foot, use this discoloring agent, can remove the color in the product effectively.
The Oleum Gossypii semen oil foot is the tankage that produce in the Oleum Gossypii semen treating process, is also referred to as the cotton oil pin.It is that aterrimus is thick that this oil foot outer appearnce is similar to pitch.Because its color is dark and be difficult for removing, it is difficult therefore it to be carried out deep processing.The industrial cotton oil pin that utilizes is about to this oil foot alkali soapization as the raw material of making soap, soap stock, owing to still be aterrimus after the saponification, need carry out repeatedly alkali refining again color is alleviated gradually.But because of behind three alkali refinings, its color no longer reduces, and is that the made soap base of raw material can only be used to make low-grade soap or soap powder with the cotton oil pin therefore.
The purpose of this invention is to provide a kind of chemical reagent that is used for the decolouring of cotton oil pin, cotton oil pin discoloring agent uses this discoloring agent in the cotton oil pin course of processing, can remove the color in (or alleviating) product effectively, improves the utility value of cotton oil pin.Simultaneously, using this discoloring agent also can have the technical process of simplifying in the existing industrial production, improves the utilization ratio of cotton oil pin.
Cotton oil pin discoloring agent provided by the present invention is characterized in that adopting hydrogen peroxide (H 2O 2) as discoloring agent, in the deep-processing process of cotton oil pin, hydrogen peroxide can be removed the color of (or alleviating) cotton oil pin goods effectively under alkaline condition.Be that the raw material alkaline saponification is made in the course of processing of soap base with the cotton oil pin, can add discoloring agent of the present invention, and carry out saponification and alkali refining repeatedly by former technology, promptly at first carry out saponification reaction, after the saponification, wherein residual Oleum Gossypii semen is carried out alkali refining again with alkali and cotton oil pin, it is characterized in that carrying out the secondary alkali refining, and add the discoloring agent hydrogen peroxide during alkali refining in the second time, through the effect of the oxidation bleaching of hydrogen peroxide, can remove the color of (or alleviating) soap base effectively.The addition of discoloring agent is for the second time during alkali refining 0.02~0.3% of solution weight.Use discoloring agent provided by the invention, in the saponification of cotton oil pin, alkali refining processing, only need carry out the secondary alkali refining, just can obtain the soap base of colourless (or the very light beige of color), therefore, can shorten its work flow, and the yield of raising product, this soap base can be used for making medium-to-high grade soap or soap powder simultaneously.Below by example technology of the present invention is described further.
Embodiment cotton oil pin soapmaking base
Utilize conventional cotton oil pin processing saponification soapmaking base technology, in second time during alkali refining, add in solution and contain 30% aqueous hydrogen peroxide solution, making the concentration (weight) of hydrogen peroxide is 0.06%.Obtain colourless soap base behind the alkali refining through the second time.The reacted product of hydrogen peroxide and Oleum Gossypii semen does not have influence to product, need not to handle.
By above-mentioned, use discoloring agent of the present invention, not only can simplify existing work flow, make the cotton oil pin directly can be used for the raw material of washing composition (soap or soap powder), can make full use of this resource of cotton oil pin again, and improve its use value.

Claims (2)

1. a cottonseed oil foot decolorant is characterized in that adopting hydrogen peroxide to make discoloring agent.
2. one kind is used the Oleum Gossypii semen oil foot of the described discoloring agent of claim 1 to carry out saponification, alkali refining soapmaking base working method, it is characterized in that its employing secondary alkali refining reaction, and when the second time, alkali refining reacted, the weight of pressing alkali refining solution added 0.02~0.3% discoloring agent hydrogen peroxide.
