Abstract
Telah dilakukan penelitian tentang perhitungan mekanisme reaksi asetalisasi benzaldehida menggunakan katalis asam (HCl) dengan metode komputasi (Ab-Initio). Penelitian ini bertujuan untuk mengetahui energi tiap tahapan reaksi asetalisasi benzaldehida. Perhitungan mekanisme dilakukan menggunakan metode ab initio dari hyperchem versi 8.0 denngan basis set 3-21G dan 6-31G*. Hasil perhitungan energi tiap tahapan reaksi asetalisasi selalu mengalami perubahan. Tahap awal pembentukan Benzylideneoxonium memiliki selisih energi dengan benzadehid sebesar 468,2204 kJ/mol dan 517,5909 kJ/mol tahap terakhir pembentukan Benzaldehyde-dimethyl-acetal memiliki selisih energi dengan benzaldehida sebesar -51,9294 kJ/mol dan -6,8003 kJ/mol. Selisih energi tertinggi pada tahap pembentukan Methoxy-phenyl-methanol yaitu 1299,2017 kJ/mol dan 1399,6171 kJ/mol serta selisih energi terendah terjadi pada tahap Benzaldehyde-dimethyl-acetal
