The reaction flask was washed with a solution of 25 grams of sodium hydroxide in 250 cc of water. The combined alkaline solutions were heated to boiling for 5 minutes. A small amount (6 grams) of alkali-insoluble material remained and was filtered off. Sulfuric acid (62% H2SO4 content) was then added at room temperature dropwise under stirring to the filtrate until a pH of 10.3 was reached. This required about BO grams of the acid. The monosodium salt of bis-(3,5,6-trichloro-2-hvdroxyphenyl) methane precipitated out of solution and was filtered and then washed with 200 cc of water. The salt was then sus-... [Pg.760]

In the literature a number of different techniques for the preparation of a-sulfo fatty acid esters can be found. There is equipment for small-scale and commercial scale sulfonation. Stirton et al. added liquid sulfur trioxide dropwise to the fatty acids dispersed or dissolved in chloroform, carbon tetrachloride, or tetrachoroethylene [44]. The molar ratio of S03/fatty acid was 1.5-1.7 and the reaction temperature was increased to 65 °C in the Final stage of sulfonation. The yield was 75-85% of the dark colored a-sulfonated acid. The esterification of the acid was carried out with either the a-sulfonic acid alone, in which case the free sulfonic acid served as its own catalyst, or with the monosodium salt and a mineral catalyst.

One hundred and forty-four grams (0.60 mole) of the dry monosodium salt of p-hydroxyphenylarsonic acid [Org. Syntheses Coll. Vol. 1, 490 (1941)] is added portionwise with stirring and cooling to 450 ml. of concentrated sulfuric acid. A mixture of 39 ml. of nitric acid (sp. gr. 1.4) and 39 ml. of concentrated sulfuric acid is added with continuous stirring and sufficient cooling to hold.the temperature of the reaction mixture below 0°. The temperature is then allowed to rise to 10° over a period of several hours. The reaction mixture is poured into 2250 ml. of water and allowed to stand for 24-48 hours. The precipitated 3-nitro-4-hydroxyphenylarsonic acid is filtered off and washed with saturated aqueous sodium chloride solution until free of sulfuric acid and then with water until free of salt. The dry product is obtained in a yield of 65-75%. [Pg.224]
