What is D-Limonene and how is it identified?

D-Limonene has CAS 5989-27-5, molecular formula C₁₀H₁₆ and molecular weight 136.24. It is also named (R)-p-mentha-1,8-diene and is a major component of orange peel oil.

What is D-Limonene used for?

D-Limonene is used as a renewable cleaning solvent and industrial degreaser, especially for printing ink removal, concrete or tar cleaning and stain removal. It is also used as a fragrance or flavor ingredient and can replace selected petroleum or chlorinated solvents in formulations.

Which specifications should be confirmed when purchasing D-Limonene?

Confirm limonene assay, optical rotation, refractive index, density, color, odor and peroxide value. Technical grades commonly specify limonene content of at least 94%, with the exact value depending on the supplier and intended use.

Why is optical rotation important for D-Limonene?

D-Limonene is the dextrorotatory enantiomer, while dipentene or limonene blends may contain a racemic or mixed isomer profile. Checking optical rotation helps confirm that the material is the D-enantiomer and matches the fragrance, solvent or formulation requirement.

Product Description

D-Limonene, CAS 5989-27-5, is a naturally derived cyclic monoterpene also named (R)-p-mentha-1,8-diene; the EC/EINECS number is 227-813-5.

Synonyms: (R)-p-Mentha-1,8-diene; (+)-Dipentene; 1-Methyl-4-(1-methylethenyl)cyclohexene; Citrus stripper oil.

CAS: 5989-27-5.

Molecular formula: C₁₀H₁₆.

Molecular weight: 136.24.

EC number: 227-813-5.

It is a clear, colorless liquid with a light, sweet orange aroma that is insoluble in water and soluble in alcohol and most organic solvents.

Typical properties include melting point about -74 °C, boiling point about 175.4-176 °C, flash point about 43 °C, relative density about 0.84 and refractive index about 1.472.

It is widely used as a renewable cleaning solvent and industrial degreaser, including printing-ink removal, concrete or tar cleaning, stain removal and parts washing.

It is also used as a fragrance or flavor ingredient and can replace selected petroleum or chlorinated solvents in formulations.

Confirm limonene assay, optical rotation, refractive index, density, color, odor and peroxide value; technical grades commonly specify at least 94% limonene.

Store in tightly closed containers in a cool, ventilated flammable-liquid area away from heat, sparks, open flames and strong oxidizers, and protect from air and light to limit oxidation and peroxide formation.
