Embodiment Construction

[0009] A cardanol polyoxyethylene ether sulfate ammonium salt, which has the following structural formula:

[0010]

[0011] Wherein, n=2-25.

[0012] In the present invention, cardanol polyoxyethylene ether prepared from cardanol extracted from natural cashew nut shell is used as raw material, and then reacted with sulfamic acid to obtain cardanol polyoxyethylene ether sulfate ammonium salt with excellent performance , the mechanism is: sulfamic acid first forms SO 3 and NH 4 The complex compound is reacted with phenol ether to obtain cardanol polyoxyethylene ether sulfate ammonium salt. The equation of its reaction is as follows:

[0013]

[0014] The preparation method of polyoxyethylene cardanol sulfate ammonium salt is characterized in that polyoxyethylene cardanol is put into a reactor equipped with a stirrer, heated to 110-150°C, and fully stirred at a constant temperature Put in sulfamic acid and catalyst, react at constant temperature and under stirring for ...

Abstract

The invention provides cardanol polyoxyethylene ether ammonium sulfate and a preparation method thereof. The preparation method comprises the following steps of: adding cardanol polyoxyethylene ether into a reactor provided with a stirrer, fully stirring at constant temperature and adding sulfamic acid and a catalyst; and stirring, reacting at constant temperature for 7 to 9 hours, neutralizing excessive sulfamic acid in the reaction system to a pH value of 8 to 10 by using sodium hydroxide, cooling, and filtering to prepare the cardanol polyoxyethylene ether ammonium sulfate. The cardanol polyoxyethylene ether which is prepared from natural cardanol is taken as a raw material for production, the negative influence of petroleum-synthesized cardanol polyoxyethylene ether ammonium sulfate on environment is avoided, the defects of more waste acid, high product saltness, complex technical control operation and the like in the technical route that the alkylpheol polyoxyethylene ether and a sulfating agent are directly reacted are overcome, and sulfated products is not needed to be neutralized by ammonia water or liquid ammonia.

Description

technical field [0001] The invention relates to an organic compound and a preparation method thereof, in particular to a cardanol polyoxyethylene ether sulfate ammonium salt and a preparation method thereof. Background technique [0002] Alkylphenol polyoxyethylene ether is one of the main varieties of polyoxyethylene nonionic surfactants, which have outstanding advantages such as strong permeability, high detergency, good compatibility, and rapid dissolution. However, due to its strong degreasing ability to skin and hair, greater irritation to skin, and weak foaming ability, its application as an active raw material for daily cleaning products is limited to a certain extent. Therefore, it is imperative to develop downstream products with more comprehensive performance using alkylphenol polyoxyethylene ether as raw material. Alkylphenol polyoxyethylene ether sulfate ammonium salt was developed by Europe and the United States in the 1980s. This product not only maintains the...
