I. Core Product Matrix: The "Basic Grain" and "Specialty Vegetable" of Fine Chemicals

Priti's product portfolio is not simply a collection of chemical raw materials, but a well-thought-out dual-engine layout of **"basic large-scale products + distinctive high value-added products"**.

Diphenylamine (DPA) – Annual production capacity of 20,000 tons

Diphenylamine (CAS No.: 122-39-4) is one of the most produced and widely used basic products in the Previta product system. This seemingly simple organic compound is actually the veritable "king of intermediates" in the modern fine chemical industry chain.—It is syntheticIt is a key raw material for high-end products such as rubber antioxidants 4010NA, 4020, and IPPD, and is also an important precursor for gunpowder stabilizers, dye intermediates, and pesticide intermediates.

With an annual production capacity of 20,000 tons, Pretitech firmly holds a leading position among China's diphenylamine producers.First TierThis production capacity not only ensures a stable supply for major domestic rubber additives, dyes, and pesticide companies, but also lays a solid foundation for the company's exports to overseas markets in Asia, Europe, North America, and the Middle East.

Phenothiazine polymerization inhibitor – Annual production capacity of 5,000 tons

Phenothiazine (CAS No.: 92-84-2) is a more technologically advanced product in the Previta product portfolio. This heterocyclic organic compound with a unique tricyclic structure is...Highly efficient polymerization inhibitors indispensable in the production of acrylic acid, methacrylic acid, and their ester monomers.—It can effectively inhibit free radical polymerization throughout the entire process of monomer synthesis, distillation, storage, and transportation, ensuring that the product maintains excellent reactivity when it reaches downstream users.

Besides its application as a polymerization inhibitor, phenothiazine was also a key intermediate in the early development of antihistamines, antipsychotics, and some pesticides and dyes.Pretti's phenothiazine products are of stable quality and high purity.It has entered the qualified supplier system of many leading acrylic monomer manufacturers at home and abroad.

【High-end antioxidant KY-405 Octylated Diphenylamine, ODPA】—Annual production capacity 2,000 tons

If diphenylamine is a "mass-produced product" of Previta, and phenothiazine is a "technological product," then...Antioxidant KY-405 (octyl diphenylamine, CAS No.: 101-67-7) is Purit's "star product" targeting the high-end market.。

This is aAmine antioxidants with excellent high-temperature antioxidant propertiesIt is widely used in:

• High-end lubricating oilThis includes turbine oil, hydraulic oil, gear oil, compressor oil, and long-life engine oil.

• Lubricants for aviation, wind power, and heavy-duty industrial equipmentIt can effectively inhibit oil oxidation and deterioration even under harsh operating conditions at temperatures above 150℃.

• Rubber antioxidantsSpecial rubber products used in high-temperature environments

• Plastic antioxidantsUsed in engineering plastics, polyolefins, etc.

The KY-405 is benchmarked against in the international market.Similar products from leading international additive companies(Such as octyl diphenylamine products from companies like Infineum, Chevron Oronide, and BASF). Through continuous process optimization and quality control, Preti has reached or even surpassed international advanced levels in key indicators such as product purity, low volatility, low odor, and antioxidant efficacy, giving Chinese-made high-end antioxidants the confidence to compete with international giants for the first time.
