Product Description Product DescriptionHere is an introduction to the properties and uses of DMAPA (N,N-dimethyl-1,3-propanediamine):I. Basic Properties (Physical and Chemical Characteristics)1. Physical PropertiesAppearance and State: Colorless to pale yellow transparent liquid with a strong ammonia-like or characteristic amine odor.Melting Point: Approximately -70°CBoiling Point: 134-136°C (at atmospheric pressure)Density: 0.811 g/mL (25°C)Solubility: Easily soluble in polar solvents such as water, ethanol; may release heat when mixed with water.Volatility: Highly volatile, with vapor density greater than air; proper ventilation is required.2. Chemical PropertiesMolecular Formula: C5H13N2Structural Formula: (CH3)2NCH2CH2CH2NH2Chemical Characteristics:Belongs to aliphatic diamines, with strong basicity, capable of reacting with acids to form salts.Contains two amino groups (one secondary amino group and one primary amino group) in the molecule, exhibiting high reactivity and prone to alkylation, acylation, and other reactions.May oxidize when exposed to air for a long time; should be stored in a sealed container and kept away from oxidizing agents and acids.II. Main UsesDMAPA is an important organic intermediate widely used in chemical, pharmaceutica, textile, and other industries. Its main applications include:1. Polyurethane Industry (Core Application)Catalyst: As a tertiary amine catalyst, it is used in the synthesis of polyurethane foams (especially flexible foams) to promote the cross-linking reaction between isocyanates and polyols, regulating the foaming rate and foam structure.Advantage: High catalytic efficiency, improves the open-cell rate and mechanical properties of foams, commonly used in the production of furniture, car seats, thermal insulation materials, etc.2. Pharmaceutica and Pesticide Intermediates Synthesis: Used in the preparation of local anesthetics (such as analogs), antihistamines, cardiovascular etc.Pesticide Production: As an intermediate for synthesizing insecticides and fungicides (such as certain nitrogen-containing heterocyclic compounds).3. Surfactants and Textile AuxiliariesSurfactants: Used to prepare cationic surfactants (such as quaternary ammonium salts) for detergents, oilfield emulsifiers, asphalt emulsifiers, etc.Textile Auxiliaries: As a dyeing aid to improve the adsorption and levelness of dyes on fibers; or used to prepare antistatic agents and softeners.4. Epoxy Resin Curing AgentsReacts with epoxy resins to form polyamide-based curing products, enhancing the flexibility and impact resistance of epoxy resins, applied in coatings, adhesives, and other fields.5. Other ApplicationsRubber Auxiliaries: As intermediates for vulcanization accelerators or anti-aging agents.Electroplating Industry: Used to formulate brighteners for nickel and copper plating, improving the surface quality of plating layers.Petroleum Industry: As oilfield corrosion inhibitors and acidizing fluid additives to inhibit metal corrosion during oil and gas extraction.III. Safety and Storage Precautions1. HazardsHealth Risks:Vapors or liquid are highly irritating to the eyes, skin, and respiratory tract, potentially causing chemical burns.Inhalation of high-concentration vapors may lead to coughing, difficulty breathing, or even lung damage; ingestion may corrode the digestive tract.Environmental Risks: Toxic to aquatic organisms; avoid leakage into water bodies.Fire and Explosion Risks: Flammable; its vapors can form explosive mixtures with air, prone to combustion and explosion when exposed to open flames or high heat.2. Safety ProtectionWear corrosion-resistant gloves, goggles, and protective masks during operation, and work in a well-ventilated area or explosion-proof fume hood.Avoid contact with oxidizing agents, acids, acyl chlorides, and other substances to prevent violent reactions.3. Storage ConditionsStore in a sealed container in a cool, dry, and ventilated warehouse, away from fire sources, heat, and direct sunlight.Ground containers to prevent static accumulation; store separately from oxidizing agents and acids, and avoid mixed storage.Transport as a hazardous chemical, with precautions against leakage and fire during transportation.IV. Common Specifications and StandardsPurity: Industrial grade ≥99%, pharmaceutica grade ≥99.5%Packaging: Usually packed in 160 kg galvanized iron drums or plastic drums; tank truck transportation can also be provided as needed.Regulatory Compliance: Must comply with relevant safety standards such as the Regulations on the Safety Management of Hazardous Chemicals (China) and OSHA (USA). For more detailed technical parameters or safety data, it is recommended to refer to the product MSDS or consult the supplier.Product Packaging Company ProfileDalian Sinobio Chemistry Co.,Ltd was established in 2011 and located in beautiful costal city .We focus on fungicide and water treatment's production and export over 14 years.Sinobio is a group company who has 2 production sites in China: One is in Jiangxi province which produce fungicide such as lsothiazolinon,BIT,Zinc Pyrithione ,etc.Our products can be widely used in the fields of oil-field water injection, pulp and paper making,water treatment,marine paint, wood, plastic leather,paint coating,cosmetics,personal care products, textiles, fiber, building materials,etc. for sterilization,corrosion prevention and mildew prevention.In particular, it has been widely recognized in the application of sterilization,algae killing,scale inhibition and corrosion inhibition of circulating cooling water in petrochemical, power metallurgy and other industrial fields.The other one was located in Gansu province which produce water treatment chemicals such as ATMP, HEDP,THPS,TXP etc .Our company has realized the research and development, production and sales of products and provided a series of services such as water treatment engineering solutions.
