Acetal
Colorless liquid. Volatile. The molecular weight is 118.18. The boiling point is 103.2 ° C. The relative density is 0.8314. The refractive index is 1.3834. Soluble in water, acetic acid, heptane, butanol. Miscible with ethanol and ether. Easy to polymerize after long-term storage. Stable in alkaline. It is mainly used as a solvent. Also used in the synthesis of dyes, plastics and spices. Made from acetaldehyde and ethanol in the presence of anhydrous calcium chloride and a small amount of inorganic acid.
Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. used a capillary column to determine the purity and impurity co
ntent of the fragrance acetal.
