2017 results about "Benzene sulfonate" patented technology

Alkyl benzene sulfonate (ABS) is an organic chemical compound primarily used as a surfactant. Its chemical formula is C 6H 5CnH 2n+1, where n lies between 10 and 16. ABS is a major component of anionic detergents. Alkyl benzene sulfonates have two types depending on their chain structures: branched and linear chain.

Method for preparing high-alkali value (TBN400) synthesized calcium alkyl benzene sulfonate

The invention provides a method for preparing high base number (TBN400) synthetic calcium alkyl-benzene sulfonate. The method comprises the following steps of: adopting a mixed acid of long-chain linear alkyl-benzene sulfonic acid and high-boiling heavy alkyl-benzene sulfonic acid, calcium oxide and/or calcium hydroxide, low-carbon alcohol, alkaline-earth metal halide or nitrate, and a mixture of alkaline-earth metal alkylphenol or alkaline-earth metal alkylphenate and polyisobutylene succinic anhydride for a neutralization reaction in the presence of a solvent and cutback oil at a temperature of between 40 and 80 DEG C; then, passing through carbon dioxide to a product of the neutralization reaction at a temperature of between 40 and 60 DEG C for a carbonation reaction; and producing high base synthetic alkyl-benzene sulfonate with a total base number (TBN) of 400mgKOH/g by adopting a process of a one-step method. The product is divided into high-base number (TBN400) synthetic alkyl-benzene sulfonate containing chlorine and high-base number (TBN400) synthetic alkyl-benzene sulfonate without the chlorine. The product produced by adopting the method with low viscosity, small turbidity, easy filtration, light color and no skin formation has the advantages of excellent high-temperature detergency, excellent anti-foaming property and excellent heat storage stability.

Displacement method utilizing compound containing sulfonate negative non-surface active agent

The invention relates to a displacement method utilizing a compound containing sulfonate negative non-surface active agent, which mainly solves the problems in the prior art that the displacement efficiency of the displacement agent containing the surface active agent is poor under the high-temperature high-salt condition, the application concentration is high and alkali in a tertiary composite displacement causes the corrosion and scale accumulation harm on the stratum and an oil well. The displacement method adopts alkylphenol polyoxyethylene ether benzene sulfonate, polymer and water to be mixed into displacement agent compound, under the magnesium chloride injection water condition that the displacement temperature is 30 to 83DEG C, the total mineralization degree is more than 8000mg/L, magnesium ion is more than 200mg/L and calcium ion is more than 30mg/L, dehydrated crude oil is contacted with the compound, so that the crude oil in a core can be adequately displaced, and the compound comprises the following components in parts by weight: (1) 0.01 to 5 parts of alkylphenol polyoxyethylene ether benzene sulfonate; (2) 0.01 to 3 parts of polymer; and (3) 90 to 99.9 parts of injection water. Due to the adoption of the technical scheme, the problems can be well solved, and the displacement method can be used in the tertiary oil recovery of an oil field.
