Acetophenone: Industrial Grades & Application Guide
Product Overview & Core Properties
Acetophenone (CAS 98-86-2), also known as acetylbenzene, is the simplest aromatic ketone compound. It appears as colorless to pale yellow transparent liquid with a characteristic sweet hawthorn-like odor. It has excellent solubility for various resins, cellulose ethers, rubbers and oils, with high boiling point, low volatilization rate and stable chemical properties. As a multifunctional industrial chemical, it serves both as a high-performance solvent and as a basic intermediate for organic synthesis, widely used in coatings, spices, pharmaceuticals, dyes and other industries.Grade Classification & Specification Differences
We supply two mainstream commercial grades of acetophenone, differentiated by purity and impurity control to adapt to production scenarios of different precision requirements.Industrial Grade (≥99.0% purity)
Standard mass-produced specification with stable basic performance and cost advantages. Moderate impurity control meets the needs of conventional industrial scenarios, suitable for bulk use as solvent and general chemical auxiliary.
High Purity Grade (≥99.5% purity)
Refined by rectification process, with low moisture, low heavy metal residue and lighter color. It has fewer side reaction impurities, suitable for fine chemical synthesis, fragrance blending and pharmaceutical intermediate production with strict quality requirements.
Key Industrial Application Scenarios
High-Boiling Solvent for Coatings & Resins
As a high-boiling point solvent, acetophenone is widely used in nitrocellulose coatings, resin varnishes, ink formulations and rubber processing. It has strong dissolving capacity for cellulose acetate, alkyd resin and natural rubber, with slow volatilization speed, which helps to improve the leveling property of coating film and reduce surface defects such as pinholes and orange peel. It is an ideal co-solvent for high-performance coatings and adhesive systems.
Fragrance & Flavor Industry
Acetophenone is an important raw material for the synthesis of phenylethanol, phenylethyl acetate and other floral fragrances. Its own persistent sweet aroma also makes it a common fixative for soap fragrances and industrial flavors. It can blend well with other spice components to enhance the richness and durability of fragrance. High purity grade is required for fragrance production to avoid odor deviation caused by impurities.
Pharmaceutical & Fine Chemical Intermediate
In the pharmaceutical industry, acetophenone is used as an intermediate for the synthesis of antipyretic analgesics, cholagogic drugs and other active pharmaceutical ingredients. It is also a key raw material for the production of photosensitizers, antioxidants and dye intermediates. Production links with high requirements for product purity and yield shall adopt high purity grade to reduce side reactions and improve finished product qualification rate.
Other Industrial Auxiliary Uses
It can also be used as plasticizer for plastic products, denaturant for industrial alcohols, and organic synthesis intermediate for agricultural chemical formulations, with wide industrial adaptability.Selection Guide: Matching Grade to Your Production
Choose Industrial Grade when: used as bulk solvent for general coatings, inks and rubber processing; used as general industrial auxiliary with no strict requirement on impurity and color. This grade balances performance and cost, suitable for long-term mass procurement.Choose High Purity Grade when: used for fragrance synthesis, pharmaceutical intermediate production, fine chemical synthesis; production scenarios with strict requirements on product color, impurity content and reaction yield. This grade ensures stable reaction and high finished product quality.
Storage & Handling Notes
Acetophenone is a flammable liquid. It shall be stored in a cool, ventilated warehouse away from fire sources and heat sources. The packaging shall be kept sealed to avoid contact with oxidizing agents and long-term exposure to air, which may cause color deepening. Handle with care during loading and unloading to prevent packaging leakage.Common Purchasing FAQs
Q1: Does acetophenone dissolve in water?Acetophenone is slightly soluble in water and miscible with most organic solvents such as ethanol, ether, benzene and chloroform, with excellent solubility for most resin materials.
Q2: Can industrial grade acetophenone be used for fragrance production?
It is not recommended. Impurities in industrial grade products may cause odor deviation and affect fragrance quality. High purity grade shall be selected for fragrance and fine chemical production.
Q3: What are the advantages of acetophenone as a solvent compared with other ketone solvents?
It has higher boiling point and slower volatilization rate than acetone and butanone, which can extend the drying time of coating film and improve leveling property. It also has stronger dissolving capacity for special resins, with wider application range.
Q4: What packaging specifications are available?
We support standard bulk packaging and small-batch customized packaging, which can be matched according to your production dosage and transportation requirements.
