.Г1олучаема таким способом калыпкмш  соль т)поксиглутарО1Ш1 1 кислоты загр знена нродуктами осмолептг  ксилозы, содержит некоторое количество кальциевой солн кснлоповоГ: );пслоты и незначительное количество калыгие1 01г солтг a30THoil кислоты. При нромывке кальциевой соли триоксиглутаровой кислоты даже болыиим количеством гор чей воды не удаетс  далить эти вещества, так как oini невозвратимо адсорбированы кальциевой солью триоксиглутароио з пслоты или образуют с нею комплексные соедииепи . Поэтому при разложении ее cepnoii кислотой получаютс  загр зненные растворы триоксиглутаровой кислоты.Glypkmsh salt t) coxyglutar O1SH1 1 acid is obtained in this way, which is contaminated with the products of osmoleptic xylose and contains a certain amount of calcium sunshine:); pslot and an insignificant amount of calygee101g saltg a30THoil acid. When cutting the calcium salt of trioxyglutaric acid, even with a large amount of hot water, these substances cannot be removed, since oini is irreversibly adsorbed by the calcium salt of trioxyglutario sludge or forms complex compounds with it. Therefore, by decomposing its cepnoii acid, contaminated trioxyglutaric acid solutions are obtained.

Несмотр  на нрименение большого количества активированного угл , не удаетс  нолучить достаточную очист1;у от загр зн ющих веществ, поэтому при кристалл гзацин нолучнт1 триоксиглутаровую кислоту в чистом виде, пригодном дл  применени  в И1пцеио11 иромышленности, невозможно .

Все это весьма усложн ет нронзводство н обусловливает большие потери триоксиглутаровой кислоты.Despite the use of a large amount of activated carbon, it is not possible to obtain sufficient purification of contaminants, therefore, when a crystal is obtained, a trioxyglutaric acid in its pure form, suitable for use in the industry, is impossible. Newly required K1) trioxyglutaric acid is required. All this greatly complicates the production and causes large losses of trioxyglutaric acid.
