Directory Guidance on Rosin Amine

Basic Info

Rosin Amine (CAS Registry Number: 61790-47-4), also known historically by its primary active component Dehydroabietylamine, is a primary aliphatic amine derived from the chemical amination and reduction of natural rosin acids (primarily abietic acid). Structurally, it combines a bulky, rigid hydrophenanthrene ring system with a highly reactive terminal primary amino group (-NH₂).

This unique polycyclic hydrophobic skeleton paired with a polar amine headgroup grants Rosin Amine exceptional film-forming capability, strong surface adsorption on metal substrates, and excellent solubility in organic media. Manufactured under precise amination and purification by Shandong Zhishang Chem Co., Ltd., our Rosin Amine is a versatile chemical intermediate widely applied in oilfield acidizing corrosion inhibition, cationic asphalt emulsification, mineral flotation, and specialty surfactant synthesis.

Product Packaging

Rosin Amine Application

Due to its distinctive hydrophenanthrene ring structure and strong surface affinity, Rosin Amine fulfills key roles across critical industrial sectors:

Oilfield Acidizing & Pipeline Corrosion Inhibitors: Adsorbs strongly onto carbon steel surfaces to form a dense, hydrophobic protective monolayer, protecting drilling pipes and refinery units against acidic corrosion (H₂S, CO₂, HCl).

Asphalt Emulsifiers & Road Construction: Functions as a cationic precursor in quick-setting and medium-setting asphalt emulsions, enhancing adhesion between bitumen and acidic mineral aggregates (such as granite and quartz).

Mineral Flotation Collector: Acts as a selective collector in the froth flotation of silicate minerals, oxide ores, and industrial non-metallic salts.

Specialty Surfactants & Fuel Additives: Precursor for synthesizing quaternary ammonium salts, corrosion-resistant lubricants, cleaning additives, and microbial control agents.

FAQ

Q1: What structural feature makes Rosin Amine more effective in high-temperature corrosion inhibition than linear fatty amines?

A: Rosin Amine contains a bulky, rigid tricyclic (hydrophenanthrene) hydrocarbon core. Unlike linear alkyl chain amines (e.g., oleylamine or stearylamine), this bulky polycyclic structure creates a thicker, more sterically hindered hydrophobic film on metal surfaces, offering superior thermal stability in high-temperature acidizing environments.

Q2: Is Rosin Amine soluble in water or organic solvents?

A: In its neutral free-amine state, Rosin Amine is virtually insoluble in water but highly soluble in common organic solvents including ethanol, toluene, xylene, diesel, and mineral spirits. When neutralized with organic acids (such as acetic or formic acid) or mineral acids, it becomes readily dispersible or soluble in water as an amine salt.

Q3: How should Rosin Amine be handled to prevent viscosity changes or oxidative darkening?

A: Rosin Amine is viscous at room temperature and sensitive to prolonged high-temperature exposure in air. Store in tightly sealed drums under a nitrogen blanket in a dry, well-ventilated warehouse (15°C–30°C). Moderate heating (40°C–50°C) can be applied to facilitate pumping during production.

Q4: What standard packaging sizes are supplied for bulk export?

A: Standard packaging includes 190 kg UN-approved steel drums and 950 kg IBC totes. Batch-specific Certificates of Analysis (COA), GHS-compliant Safety Data Sheets (SDS), and pre-shipment testing samples are available upon request.

ISO 9001:2015 Certification: Governs the entire synthesis cycle—from gum rosin raw material inspection to high-pressure amination and final filtration.

ISO 14001 & ISO 45001 Compliance: Ensures rigorous environmental emission controls and workplace safety management during organic amine processing.

REACH Compliance Technical Dossier Support: Complete documentation provided for European Union importers and chemical compounders.

Dangerous Goods (DG) Logistics Alignment: Packaged and labeled in accordance with UN transportation codes for corrosive organic liquid/solid chemicals (UN 2735, Class 8).

Laboratory Quality Control & In-House Self-Inspection

To ensure consistent adsorption performance and color stability in demanding industrial formulations, every batch of Rosin Amine undergoes strict four-point internal quality screening prior to issuing the Certificate of Analysis (COA):

Amine Value & Conversion Efficiency Titration: Quantitative determination of primary amine content to confirm complete conversion of rosin acid precursors and minimal presence of unreacted resin acids.
Color & Optical Clarity Monitoring: Gardner color scale testing to maintain uniform amber appearance and prevent excessive thermal discoloration.
Solubility & Phase Stability Testing: Verified complete solubility in mineral spirits, aromatic solvents, isopropyl alcohol, and dilute aqueous acids without precipitation.
Moisture & Residue Control: Moisture analysis via Karl Fischer titration to ensure low water content (<0.5%), preventing premature hydrolytic reaction when blended into moisture-sensitive formulations.
