Description
Изобретенве относитс к новому, не опвсанному в литературе соединенвю-амв- ду 2- ва1шдан-2,2-йвоксид-5 -сульфокисло ты формулы HaUSO-j-f V./ /Г) Чх % который про вл ет пенообраауюпше свойства н может быть вспользован в качест ве вспенивател прв флотации свинцовых сульфидных руд. К предлагаемому соединению наиболее близки соединени из класса тнаиндана (бензотиофена), например S -арилсульфониламины бензо-1в1- ио |)ен-1,1-1а1И01 сиды. Известные соединени про вл ют биоло гическую активность и поэтому могут най ти применение в медицине ij. Однако они не обладают свойствами, позвол ющими использовать нх в качестве вспенивател в процессах флотации. Целью изобретени вл етс расширени арсенала вспенива,телей, использующихс при флотации суль4шдных свинцовых руд. Цель достигаетс новым амидом 2 гиаиндав-2 ,2-джжсвд-5- :ульфокислоты, который может быть в качестве вспе- нивател при флотации сульфидных свинцовых руд. . Предлагаемое соединение получают взаимодействием 2- иаш1дан-2,2 диоксид-5юульфохлорида с аммиаком. Пример. В круглодонную одногорлую колбу загружают 4О мл 25-30%-ного водного раствора аммиака и 1,2 г (0,05 моль) 2-тнаиндан-2,2-дж)ксиа-5-супьфохлорида и г нагревают смесь в течение 1О-12 ч. Затем всю массу переливают в фарфоровую чашу и раствор медленно концентрируют. Выпавший осадок фильтруют и промьгвают холодной водой. Выход 65% (0,7 г); т.пл. 210-212 0. Найдено, %: С 39,18; Н 3,21; 5 26,05. CgHgNO Sa Вычислено, %: С 38,87; Н 3,59; 325,91.The invention relates to a new, not described in the literature, compound-amvu 2-ba1shdan-2,2-yvoxide-5-sulfonic acid of the formula HaUSO-jf V. / / D) Чх% which exhibits foamy properties n can be used as a foaming agent for flotation of lead sulfide ores. The compounds of the class of tynindane (benzothiophene), for example, S-arylsulfonylamines benzo-1b1-io |) en-1,1-1a1I01, are closest to the proposed compound. The known compounds exhibit biological activity and therefore can be used in medicine ij. However, they do not have properties that allow the use of them as foaming agents in flotation processes. The aim of the invention is to expand the arsenal of foaming bodies used in the flotation of sulfide lead ores. The goal is achieved by the new amide 2 of Hyaindav-2, 2-jaxvd-5-: ulcer acids, which can be used as an enlarger in the flotation of sulphide lead ores. . The proposed compound is obtained by reacting 2-and-1-dan-2.2 dioxide-5-sulfonyl chloride with ammonia. Example. A 4O ml of a 25-30% aqueous solution of ammonia and 1.2 g (0.05 mol) of 2-tinindan-2.2-j) xia-5-supiphochloride and g are heated into a round-bottomed, single-neck flask are charged with 1 O- 12 h. Then the whole mass is poured into a porcelain bowl and the solution is slowly concentrated. The precipitate is filtered and washed with cold water. Yield 65% (0.7 g); m.p. 210-212 0. Found,%: C 39.18; H 3.21; 5 26.05. CgHgNO Sa Calculated,%: C 38.87; H 3.59; 325.91.
