Abstrak

Senyawa epoksi untuk plasticizer dapat disintesis dari metil ester asam lemak. Proses sintesis dilakukan dalam reaktor batch pada suhu operasi 60 C. Sumber oksigen yang digunakan dalam proses epoksidasi adalah hidrogen peroksida. Katalis yang digunakan merupakan senyawa berbasis asam, yaitu asam format, asam asetat, dan kombinasi keduanya. Parameter yang digunakan untuk menilai kinerja reaksi meliputi bilangan iod dan konversi ikatan rangkap atom C, serta didukung oleh sifat fisik seperti viskositas, densitas, dan titik nyala. Kinerja asam format menunjukkan bahwa konversi maksimum yang dicapai sebesar 87.47 persen dengan bilangan iod 5.84 g I2 per 100 g pada konsentrasi katalis 10 wt%. Penggunaan katalis asam asetat menghasilkan konversi maksimum sebesar 68.96 persen dengan bilangan iod 14.57 g I2 per 100 g pada konsentrasi katalis 20 wt%. Untuk katalis kombinasi, konversi maksimum yang diperoleh sebesar 79.30 persen dengan bilangan iod 9.64 g I2 per 100 g pada konsentrasi katalis total 15 wt% dengan rasio asam format terhadap asam asetat sebesar 30 banding 70. Katalis terbaik adalah asam format karena memiliki kinerja konversi tertinggi dengan penggunaan konsentrasi minimal. Hasil analisis produk menunjukkan terbentuknya senyawa metil 9,10 epoksioktadekanoat dengan konsentrasi sebesar 12.30 wt%.
