Industrial Applications of 72207-80-8
| Industry | Application | Process |
|---|---|---|
| Papermaking Industry | Dry-strength agent for papermaking | Added to pulp under alkaline conditions; synthesized via reaction of polyethylene glycol with epichlorohydrin to yield polyether polyamines or modified polyether resins, thereby enhancing inter-fiber bonding and improving dry tensile strength of paper. |
| Water Treatment | Flocculant / coagulant aid | Applied in wastewater treatment processes, where polar functional groups in the product adsorb suspended particles and bridge them together to facilitate aggregation and sedimentation during solid–liquid separation. |
| Textile Dyeing and Printing | Antistatic agent / finishing agent | Applied in fabric finishing processes; the hydrophilic polyether segments absorb ambient moisture and dissipate static charge, with the product deposited onto fiber surfaces via padding and baking to eliminate static buildup. |
| Cosmetics / Personal Care | Emulsifier / thickener | Used in emulsification processes for creams or lotions, leveraging its surfactant properties to stabilize oil-in-water emulsions; alternatively, employed to adjust aqueous-phase viscosity and improve sensory attributes. |
| Epoxy Resin Curing | Toughening agent / modifier | Incorporated into epoxy resin formulations via blending or pre-reaction to introduce flexible polyether segments, thereby reducing brittleness and enhancing impact resistance of the cured resin. |
| Coatings Industry | Dispersant / leveling agent | Added during pigment grinding or coating formulation to improve dispersion stability of pigment particles, prevent settling, and promote uniform flow and leveling during film formation. |
Manufacturing Quality Control of 72207-80-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessment of physical state and color under controlled lighting conditions. |
| Acid Value | Acid-Base Titration | Neutralization of acidic groups with standardized KOH solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation Titration | Esterification of hydroxyl groups with acetic anhydride followed by back-titration with NaOH. |
| Chlorine Content | Potentiometric Titration | Reaction with silver nitrate and detection of endpoint via silver ion-selective electrode. |
| Molecular Weight (Mn) | Gel Permeation Chromatography (GPC) | Separation by hydrodynamic volume in solution using calibrated polystyrene standards. |
| Viscosity | Capillary Viscometry | Measurement of flow time through a calibrated capillary tube under gravity at specified temperature. |
| Water Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| pH (10% aqueous solution) | pH Meter Measurement | Electrochemical determination using calibrated glass electrode in aqueous solution. |
| Ash Content | Gravimetric Analysis | Incineration at 550 C to oxidize organics, followed by weighing of residual inorganic residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and nebulization into flame or graphite furnace. |
| Residual Epoxy Chloropropane | Gas Chromatography (GC) | Separation and quantification using flame ionization detector and internal standard calibration. |
| Cloud Point | Cloud Point Determination | Temperature at which solution becomes turbid upon cooling, detected visually or optically. |
