    专利说明:

    The invention relates to an improved process for the preparation of a basic calcium sulphonate, which is used as a surfactant for. dispersion of calcium carbonate in oil. The aim of the invention is to improve the quality of the target product. The goal is achieved by conducting a series of two stages of carbonization under certain conditions and the subsequent removal of volatile impurities. Example 1 180 g of Ca (OH) 2 are dispersed in 275 g of methanol in a two-liter vessel. A solution of 290 g -alkylbenzenesulfonic acid (at 70 may.7 active ingredient in oil) in 600 g of toluene is poured into the reactor. Maintaining a temperature of 25-30 ° C, 25 g of water are added. Carboni chi begins. COj is introduced at a rate of 25 g / h, the temperature in the reactor is maintained at 25 ° C. After 75 g of carbon dioxide is introduced into the reactor, 130 g of Ca (OH) is added to the reactor, without interrupting the introduction of carbon dioxide. After the introduction of 100 g of carbon dioxide, the temperature is quickly raised to 50 ° C and at this temperature 50 g of carbon dioxide is added at a rate of 25 g / h. The introduction of COj is stopped and the mixture is stirred for 1 hour at 50 ° C. During the entire process, Ca (OH) g is found in excess in relation to the injected carbon dioxide. Then, 360 g of the diluted baby is added, and the mixture is kept to remove volatiles. The final solution from nitrogen is carried out under a race with a reduced pressure and 45 g of Kpargel DSV filter is added and the product is filtered through a Bushner 144 cm. The product H is obtained, the characteristics of which are given in the table. EXAMPLE 2. The process is carried out in the same manner as in Example 1, but with a change in the amount of carbon dioxide added at 25 and 50 ° C and the amount of water added. Comparison of the characteristics of the products A – E and the F – J products obtained according to the above-mentioned method. EXAMPLE 3 The following reagents, Sulfonic Acid 304 Toluene 600 Methanol 275 Ca (OH) j (initial charge) 180 Ca (OH) j (additive after 3 hours of introduction into COj) 130 Water 21 are charged to a two-liter batch 130 Water 21 With belt injection over g of carbon dioxide. The temperature is heated to 45 s for half an hour by simultaneously introducing another 12.5 g of carbon monoxide. The mixture was then exhausted for 1.3 hours and at the same time another 32.5 g of carbon double was introduced. Then, 344 g of the added oil is added, and volatile matter is distilled at 80 with a single blow of carbon dioxide. Finally, the product is filtered at 91.8 kg / h / m for a semi-product having the following characteristics: Slightly turbid Appearance Total alkalinity, KOH mg 413 Base count - OH, mg KOH Muddy, O, 1% 5% in Stanko-600 flocculus 3 weeks at room temperature precipitation. Kinematic viscosity, with Sediment (after 24 hours exposure), about. % Slight CaCOj in amorzh spectrum of fnom form (860 cm)
