Abstract
Sposób otrzymywania modyfikowanego haloizytu polega na tym, że haloizyt poddaje się wstępnej modyfikacji przez prażenie lub przez aktywację kwasową. Następnie dysperguje się go w rozpuszczalniku organicznym w proporcji masowej 1:4 do 1:10, a do tak przygotowanej zawiesiny wprowadza się związek modyfikujący o wzorze ogólnym 1 lub 2, gdzie R1 = łańcuch alkilowy o długości od 10 do 18 atomów węgla, R2 = grupa benzylowa lub wodór, R3 = grupa metylowa lub wodór, R4 = grupa metylowa, wodór lub, w przypadku diamidoamin, grupa amidowa dodatkowo podstawiona łańcuchem alkilowym R1, X- = jon chlorkowy, n = 1-10, wytworzony na bazie naturalnych kwasów tłuszczowych, w proporcji masowej do haloizytu od 0,2:1 do 1:1. Do kilkuminutowym mieszaniu do mieszaniny reakcyjnej wprowadza się nadtlenek organiczny w proporcji masowej do związku modyfikującego od 0,05:1 do 0,5:1. Proces modyfikacji prowadzi się w temperaturze 100-150°C przez 0,5-3 godzin, po czym rozpuszczalnik usuwa się, a osad modyfikowanego haloizytu suszy się i ewentualnie mieli się do postaci proszku.The method of obtaining modified halloysite is that halloysite is pre-modified by roasting or by acid activation. Then it is dispersed in an organic solvent in a mass ratio of 1: 4 to 1:10, and a modifying compound of general formula 1 or 2 is introduced into the suspension thus prepared, where R1 = an alkyl chain with a length of 10 to 18 carbon atoms, R2 = benzyl or hydrogen group, R3 = methyl or hydrogen group, R4 = methyl group, hydrogen or, in the case of diamidoamines, an amide group additionally substituted with the R1 alkyl chain, X- = chloride ion, n = 1-10, produced on the basis of natural fatty acids , in mass ratio to halloysite from 0.2: 1 to 1: 1. After stirring for several minutes, the organic peroxide is introduced into the reaction mixture in a mass ratio of the modifying compound from 0.05: 1 to 0.5: 1. The modification process is carried out at a temperature of 100-150 ° C for 0.5-3 hours, after which the solvent is removed and the residue of the modified halloysite is dried and eventually became a powder.
