Особенности отрицательной планарной хроматографии полистиролов
Ключевые слова:
отрицательная планарная хроматография, полистирольные стандарты, мезопористый кремнезем.
Аннотация
Процесс разделения полистирольных стандартов изучен в режиме отрицательной планарной
хроматографии (ОПХ) и колоночной ситовой хроматографии при температуре 298 К. В качестве
сорбентов были взяты силикагель КСК, силохром С-80 и пористое боросиликатное стекло. В качестве
элюентов были использованы тетрагидрофуран, толуол, бензол и их смеси.
Эксперимент показывает, что макромолекулы полимера движутся быстрее молекул элюента.
Параметр f R в случае ОПХ принимает значение больше 1 ( f R > 1). Предложены теория и метод
проведения эксперимента в режиме ОПХ полистиролов. Сопоставление рассчитанных величин k' и
p K полистирольных стандартов в режимах ОПХ и колоночной ситовой хроматографии указывает на
удовлетворительное совпадение соответствующих значений для узких фракций полистиролов при
элюировании тетрагидрофураном на силикагеле КСК, силохроме С-80 и пористом стекле МПС35.
