For chemists, researchers, and procurement specialists, a deep understanding of a chemical compound's structure and synthesis pathways is crucial for informed decision-making. 1,4-Di-tert-butylbenzene (CAS 1012-72-2) is a disubstituted benzene derivative that holds significant value as a chemical intermediate. As a trusted manufacturer and supplier, Ningbo Inno Pharmchem is pleased to share insights into the molecular science behind this versatile compound.

Understanding the synthesis and structural characteristics of 1,4-Di-tert-butylbenzene helps in appreciating its reactivity, stability, and suitability for various applications, particularly in organic synthesis and the production of specialty chemicals.

Molecular Structure and Nomenclature

1,4-Di-tert-butylbenzene, with the molecular formula C14H22, features a benzene ring substituted at the para (1,4) positions with two tert-butyl groups [-C(CH3)3]. This symmetrical structure significantly influences its physical and chemical properties. The tert-butyl groups are bulky, which can lead to steric effects in reactions involving adjacent molecules or functional groups on the benzene ring.

Synonyms commonly associated with this compound include:

  • 1,4-bis(1,1-dimethylethyl)-benzene
  • p-Di-tert-butylbenzene
  • 1,4-Bis(tert-butyl)benzene

These names reflect the structural composition and its relationship to p-xylene, where methyl groups are replaced by tert-butyl groups.

Synthesis Pathways for 1,4-Di-tert-butylbenzene

The synthesis of 1,4-Di-tert-butylbenzene typically involves the Friedel-Crafts alkylation of benzene or its derivatives. A common route involves the reaction of benzene with tert-butyl chloride or isobutylene in the presence of a Lewis acid catalyst, such as aluminum chloride (AlCl3) or sulfuric acid (H2SO4).

The reaction proceeds as follows:

Benzene + 2 * tert-butyl chloride (or isobutylene) ---[Lewis Acid Catalyst]---> 1,4-Di-tert-butylbenzene + HCl (or byproduct)

Careful control of reaction conditions, stoichiometry, and catalyst choice is essential to favor the para-substituted product and minimize the formation of ortho- and meta-isomers, as well as mono- and tri-substituted products. The bulky nature of the tert-butyl group tends to direct substitution to the para position, which aids in achieving high yields of the desired 1,4 isomer.

Purification steps, such as crystallization or distillation, are then employed to isolate high-purity 1,4-Di-tert-butylbenzene, which is critical for its use as a reliable chemical intermediate. As a dedicated manufacturer, we employ optimized synthesis and purification techniques to deliver a product that meets stringent quality standards for your R&D and production needs.
