Abstract. 4-Chlorobenzaldehyde was reacted with chlorpheniramine, Clementine, 6-Alkoxy alanine, and p-amino bazaamide to produce four new liquid crystals. It was determined if organic compounds with an amine group might produce Schiff bases with 4-Chlorobenzaldehyde. The infrared spectra of all of the major and final compounds were studied using FT-IR. Varying colors were detected, as well as different temperature. The Euro vectro - 3000A, Al-Bayt University, Jordan, was also used to calculate the carbon, hydrogen, and nitrogen ratios. Because of the applications that have been employed in their pages and to enhance their pages from air messages and migration processes, liquid crystal polymer compounds have been widely explored in the indication of tithing. To be really honest, this description is based on recent vehicle developments..
