Problems solved by technology

These preparation methods are mainly to increase the content of alkaline components in the product by selecting different accelerators, thereby increasing the alkali value of the product, but only relying on increasing the content of alkaline components in the product cannot significantly improve the performance of the detergent

Embodiment 1

[0031] Add 150 milliliters of 120# solvent gasoline, 35 grams of 150SN neutral oil, 10 grams of 10 wt % sodium hydroxide aqueous solution, 10 grams of calcium hydroxide, and 60 grams of naphthenic acid in a 500 milliliter three-necked flask with a motor stirrer and a condenser. gram (acid value 85mgKOH / g), 14 grams of dodecylphenol (the content of p-position monosubstituted alkylphenol is 75wt%), control reaction temperature at 45~60 ℃, after neutralization reaction 60min, generate neutral ring calcium alkanoate. Add 15 grams of calcium hydroxide, 20 grams of methanol, and 20 grams of n-butanol, and pass in carbon dioxide at a ventilation rate of about 80ml / min. When the flow rate reaches 70% of the theoretical value, add 15 grams of calcium hydroxide, and pass in carbon dioxide Carry out secondary carbonation reaction, when the absorption rate of carbon dioxide reaches 80%, the reaction ends. After the carbonation is completed, the temperature is raised to 120°C to remove al...

Abstract

The invention relates to a high-base number metal detergent and a preparation method thereof. The preparation method comprises the following steps of: mixing and performing a neutralization reaction on a hydrocarbon solvent, neutral oil, naphthenic acid, water, alkylphenol and calcium hydroxide and/or calcium oxide; and adding methanol and the calcium hydroxide and/or the calcium oxide; introducing carbon dioxide to perform a carbonation reaction twice; and obtaining a product through an aftertreatment process. The product has an ultra-high base number and better anti-oxidation stability.

Description

technical field [0001] The invention relates to a high-basic metal detergent and a preparation method thereof, in particular to a high-basic metal detergent composed of naphthenate and alkylphenate and a preparation method thereof. Background technique [0002] Metal detergent is one of the main additives in internal combustion engine oil. Through solubilization, dispersion and neutralization in internal combustion engine oil, it works together with other additives to inhibit the formation of carbon deposits, varnish and sludge in the oil and ensure the normal operation of the engine. Work. [0003] Naphthenate is a kind of detergent that appeared earlier in history. Overbased calcium naphthenate not only has strong detergent dispersibility, acid neutralization ability and good oil solubility, but also has excellent diffusion performance , it can not only be widely used in medium and high-grade internal combustion engine oils, but also the preferred performance improver for...
