Embodiment 1

[0025] Take 316g of refined pentadecane (en)-based resorcinol and put it into the high pressure reactor, add 0.632g of 50% potassium hydroxide solution, perform nitrogen replacement, control the vacuum degree ≥-0.095MPa, and the displacement pressure to 0.15MPa~0.25 MPa; After the nitrogen replacement is completed, the temperature is increased to 110℃~130℃ for dehydration. After the dehydration, the temperature is increased to 135℃~160℃, and 220g of ethylene oxide is added for epoxidation reaction. The temperature of the addition reaction is controlled at 130℃ ~190℃, the pressure is controlled below 0.3MPa, when the addition reaction is completed, the temperature is lowered to 65℃~75℃, then 0.34g of acetic acid is added to neutralize the pH to 5.0~8.0, and the pentadecane (ene) m-bis Phenolic polyoxyethylene ether. Put the pentadecyl (en)-based resorcinol (cardiothyl phenol) polyoxyethylene ether into the esterification reactor, pass nitrogen for replacement, and increase the t...

The invention further discloses a preparation method and application of the pentadecane (ene) naphthalenediol polyoxyethylene ether sulfo succinate monoester disodium salt as a surfactant. Please see the structural formula in the description.

Description

Technical field [0001] The invention relates to the technical field of surfactants, in particular to disodium pentadecyl (en)-based m-diphenol (cardiac phenol) polyoxyethylene ether sulfosuccinic acid monoester and its preparation method and application. Background technique [0002] Sulfosuccinate is a kind of mild anionic general-purpose surfactant. It has excellent emulsifying and dispersing properties, fine and rich foam, no slippery feeling, very easy to rinse, and can be used in various liquid detergents. The consumption of sulfosuccinate surfactants in the United States, Japan and some industrially developed countries in Europe has been increasing year by year, and has a tendency to gradually replace other anionic surfactants in this field. Only the United States has developed industrial products in the 1990s. For more than ten series and dozens of varieties, the annual output exceeds 10,000 tons. [0003] At present, there are no relevant reports on the surfactants of pent...
