Product Introduction
4-tert-Butylphenol, often abbreviated as PTBP (CAS 98-54-4), is an important organic chemical intermediate belonging to the alkylphenol family. It appears as white crystalline flakes or needles with a characteristic phenolic odor. 4-tert-Butylphenol (CAS 98-54-4) is highly valued for its ability to modify the properties of synthetic resins, imparting improved oil solubility, stability, and chemical resistance. It serves as a fundamental building block in the polymer industry, particularly for the synthesis of polycarbonate and high-quality phenolic resins used in adhesives and coatings.

Applications
Polycarbonate Production Used as a chain terminator (end-capping agent) in the synthesis of polycarbonate. It helps regulate the molecular weight and improves the processability and thermal stability of the final plastic.
Phenolic Resin Synthesis PTBP is reacted with formaldehyde to produce oil-soluble phenolic resins. These resins are essential for high-performance adhesives, printing inks, and protective coatings for metal.
Antioxidants and Stabilizers It serves as an intermediate in the production of various antioxidants and light stabilizers used to protect plastics and rubbers from aging and UV degradation.
Fragrance and Flavor Intermediate In the fine chemical industry, it is utilized as a precursor for the synthesis of 4-tert-butylcyclohexanol and its esters, which are widely used in perfumes and soaps for their woody or floral scents.
Packaging
Standard industrial packaging options for 4-tert-Butylphenol include:
-
25kg plastic-lined woven bags or kraft paper bags (Standard export palletized).
-
500kg or 1000kg jumbo bags (FIBC) for large-scale resin manufacturing plants.
-
Specialized moisture-proof packaging available upon request to maintain crystalline integrity.
Storage
4-tert-Butylphenol should be stored in a cool, dry, and well-ventilated warehouse. Containers must be kept tightly sealed and protected from direct sunlight. As an organic phenol, it should be kept away from strong oxidizing agents, strong bases, and halogens. Protect from heat and open flames. Proper dust control measures should be implemented to prevent dust accumulation in the storage area.

FAQ
Polymer and Resin Applications
-
Q1: How does PTBP affect the viscosity of phenolic resins? A1: The inclusion of the tert-butyl group increases the oil solubility and reduces the brittleness of the resin, allowing for better viscosity control in varnish and adhesive formulations.
-
Q2: Why is the “Free Phenol” content so important? A2: High levels of free phenol can lead to unwanted odors, skin irritation in final products, and can interfere with the curing rate of high-performance resins.
-
Q3: Can PTBP be used in food-contact materials? A3: It is widely used in resins for coatings and adhesives; however, compliance depends on the specific regional food-contact regulations (e.g., FDA or EU 10/2011). Please consult our technical team for regulatory support.
Safety and Logistics
-
Q1: Is 4-tert-Butylphenol hazardous to the skin? A1: Yes, like most phenols, it is a skin and eye irritant. Proper PPE, including gloves and safety goggles, must be worn during handling.
-
Q2: Is it stable during long-distance shipping? A2: It is physically stable; however, it should be kept cool. In very hot climates, the flakes may show some clumping (caking), though this does not affect chemical purity.
-
Q3: What is its environmental classification? A3: It is classified as hazardous to the aquatic environment (Category 1). Spill containment and proper waste disposal are mandatory.
