Pierwszenstwo: Zgloszenie ogloszono: 01.10.1974 Opis patentowy opublikowano: 30.12.1975 82409 KI. 42i,10/04 MKP- G01k 11/12 CZYTGLNIA r -- f ¦ Twórcywynalazku: Barbara Grossman, Edyta Rokicka, Andrzej Kus, Jan Wasiak, Aleksander Szymanski, Henryk Zajac, Józef Hejwowski, Janina Oleszkiewicz Uprawniony z patentu tymczasowego: Politechnika Lódzka, Lódz (Polska) Cieklokrystaliczny wskaznik temperatury Przedmiotem wynalazku jest cieklokrystaliczny wskaznik temperatury.Cieklokrystaliczne wskazniki temperatury stanowia mieszaniny zwiazków tworzacych faze cieklokrysta¬ liczna typu cholesterolowego i wykazujace wlasnosci selektywnego odbicia swiatla. Zmiana odbijanej dlugosci fali, czyli zmiana ich zabarwienia, zalezy w pierwszym rzedzie od temperatury. Jako zwiazki tworzace faze cieklokrystaliczna typu cholesterolowego sa uzywane estry kwasów tluszczowych i cholesterolu, takie jak ofeinoweglan cholesterolu, pelargonian cholesterolu, kaprylian cholesterolu i inne. Ponadto cieklokrystaliczne wskazniki temperatury zawieraja wypelniacz w postaci rozdrobnionego tlenku niklu lub molibdenu badz chromu lub sadzy, które absorbuja promieniowanie nie ulegajac selektywnemu odbiciu. Przedzial temperatury, w którym dziala wskaznik jest zalezny od skladu jakosciowego i ilosciowego mieszaniny.Zgodnie z wynalazkiem stwierdzono , ze cieklokrystaliczny wskaznik zawierajacy 84-90% mieszaniny estrów cholesterolu z kwasami powstalymi w wyniku hydrolizy oleju rzepakowego, 9-11% propionianu cholesterylu oraz 1—1,5% p-nitrobenzoesanu cholesterylu, w którym wypelniacz stanowi tlenek kobaltu, wykazuje zmiany zabarwienia w przedziale temperaturowym 35—42°C.Cieklokrystaliczny wskaznik wedlug wynalazku jest szczególnie przydatny, ze wzgledu na przedzial temperatury, w diagnostyce medycznej. Stabilnosc chemiczna i fizyczna wskaznika, a nadto niski koszt jego skladników stanowia dodatkowa jego zalete. PL
