Aminasi Hyperbranched Polyglycerol (HPG) Dengan Gas Amonia

Dwinna Rahmi

Abstract


Hyperbranched polyglycerol amine (HPG-amina) adalah salah satu senyawa amin yang berpotensi diterapkan pada berbagai industri. Saat ini HPG-amina disintesis dari proses aminasi HPG dengan diethylamine melalui reaksi tosilasi. Metoda ini sulit bila ditingkatkan menjadi skala industri dan juga kurang ramah lingkungan. Penelitian ini bertujuan melakukan proses aminasi dengan menggunakan gas amonia dalam reaktor tertutup. Penambahan katalis logam Fe dan Ni, suhu reaksi dan waktu proses berpengaruh signifikan terhadap produk yang dihasilkan. Dari hasil uji gugus fungsi HPG-amina yang diproses dengan penambahan katalis Ni pada suhu 100 oC selama 8 jam menunjukkan adanya kandungan amina primer –CONH2 dan amina sekunder R-NH dengan kandungan N total sebesar 6,7 ppm dan amonia bebas sebesar 3,4 ppm. Aminasi yang dilakukan tanpa penambahan katalis dan penambahan katalis Fe menghasilkan HPG-amina dengan sedikit gugus R-NH dan C=O yang belum bereaksi dengan amonia. Suhu proses di atas 100 oC menjadikan HPG-amina berwarna lebih gelap dan bahkan terlihat keruh. Proses yang dilakukan lebih dari 8 jam menurunkan kandungan N total menjadi 5,8 ppm.
