Substitution Reaction of Hydroxy of Citronellol with Chloride Using A Mixture of Ammonium Chloride and Sulphuric Acid

Abstract

Substitution reaction of hydroxy of citronellol with chloride using a mixture of ammonium chloride (NH₄Cl) and sulphuric acid (H₂SO₄) has been conducted. The citronellol was obtained from the reduction of citronellal using sodium borohydride (NaBH₄) at room temperature for 30 minutes. Substitution of hydroxy of citronellol with chloride ion was carried out at 80 ^oC and molarity ratio of citronellol and NH₄Cl 1:1, 1:2; 1:3; and 1:4 respectively. Identification of the product by gas chromatography-mass spectrometry (GC-MS) showed that the substitution reaction produced 2-isopropyl-5-methyl-1-chlorocyclohexane compound with rendemen 64,49 % in mol ratio of 1:4. The infra red (IR) analysis showed that there was a vibration at wave number 763 cm^-1 which is a typical C-Cl vibrations.
