Description
Najdluzszy czas trwania paleniu do dnia 1 marca 1944 r.W patencie glównym Nr 10094 opisano sposób otrzymywania produktów konden¬ sacji aldehydów i fenoli, który polega na tern, ze aldehydy kondensuje sie z p-chlo- rofenolem lub p-bromofenolem lub ich po- chodnemi, zawierajacemi obojetne produk¬ ty podstawienia.Ponizej przytacza sie dalszy przyklad otrzymywania podobnych produktów kon¬ densacji.Przyklad. W 800 cz. 80% -ego kwasu siarkowego rozpuszcza sie 75 cz. o-sulfo- benzaldehydu, nastepnie dodaje 103 cz, p- chlorofenolu i miesza w ciagu okolo 24 go¬ dzin w temperaturze 30°C, az do calkowi¬ tego wytworzenia sie produktu kondensa¬ cji. Powstaly stop wlewa sie do wody, zo¬ bojetnia wapnem gaszonem i odsacza od gipsu. Oddzielony osad wymywa sie do¬ kladnie woda (sól wapniowa produktu kondensacji jest stosunkowo trudnorozpu- szczalna, to jednak rozpuszcza sie latwiej niz gips, wobec czego przy przemywaniu tegoz przechodzi do roztworu) i przesacz, w celu przeprowadzenia soli wapniowej w sól sodowa, zadaje soda. Weglan wapnia odsacza sie, przesacz odparowuje mozli¬ wie do sucha i wreszcie suszy w suszarce.Sól sodowa produktu kondensacji jest la- tworozpuszczalna w wodzie, podobnie jak wolny kwas sulfonowy. Zamiast o-sulfoben- zaldehydu mozna stosowac inne sulfoben-^aldehydy, np. m-sulfobenzaidehyd, Z- chto^o^S-swlfobenzaldebyd i L d.Zamiast sulfobenzaldehydów, jako ta¬ kich, mozna stosowac do kondensacji bez¬ posrednio, po odpowiedniem rozcienczeniu równiez mase otrzymana przy sulfonowa¬ niu benzaldehydów.Produkty kondensacji p-chlorofenolów ciagna na welne (futra i materjaly podob¬ ne), podobnie jak i barwniki. Traktowanie welny i materjalów podobnych zapomoca tych produktów kondensacji mozna wiec polaczyc z procesem barwienia. Welna w ten sposób obrobiona jest zabezpieczona od moli. PLThe longest duration of burning until March 1, 1944 The main patent No. 10094 describes a method of obtaining condensation products of aldehydes and phenols, which consists in condensing the aldehydes with p-chlorophenol or p-bromophenol or their derivatives, containing neutral substitution products. A further example of the preparation of similar condensation products is given below. Example. In 800 parts 80% of sulfuric acid dissolves in 75 parts. o-sulfobenzaldehyde, then 103 parts of p-chlorophenol are added and the mixture is stirred for about 24 hours at 30 ° C., until a condensation product is completely formed. The resulting alloy is poured into water, cooled with slaked lime and drained from plaster. The separated sediment is washed thoroughly with water (the calcium salt of the condensation product is relatively difficult to dissolve, but it dissolves more easily than gypsum, so when it is washed it goes into solution) and the filtrate, in order to convert the calcium salt into sodium salt, is added with soda . The calcium carbonate is filtered off, the filtrate is evaporated as dry as possible and finally dried in an oven. The sodium salt of the condensation product is soluble in water, as is the free sulfonic acid. Instead of o-sulfobenzaldehyde, other sulfobenaldehydes may be used, e.g. the mass obtained in the sulfonation of benzaldehydes is also suitably diluted. The condensation products of p-chlorophenols are drawn to wool (fur and similar materials), as well as dyes. The treatment of wool and similar materials with these condensation products can therefore be associated with the dyeing process. The wool thus treated is protected against moths. PL
