Industrial Applications of d-Glucitol, reaction products with epichlorohydrin
| Industry | Application | Process |
|---|---|---|
| Papermaking Industry | Used as a dry-strength agent to enhance tensile strength and burst resistance of paper | Added to the pulp suspension; cationic groups electrostatically adsorb onto and form hydrogen bonds with cellulose hydroxyl groups, followed by drying and curing to establish a network structure |
| Water Treatment | Used as a flocculant to promote aggregation and sedimentation of suspended particles | Dosed into the water to be treated; hydrolyzes under neutral to slightly alkaline conditions to generate positively charged polymers that neutralize the negative surface charge of colloidal particles and bridge them via adsorption |
| Textile Dyeing and Printing | Used as a fixing agent for reactive dyes to improve color fastness | Added during the post-dyeing soap-washing step; epoxy groups in the molecule react with cellulose hydroxyl groups to form covalent crosslinks that immobilize the dye |
Manufacturing Quality Control of d-Glucitol, reaction products with epichlorohydrin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 205 nm based on peak area comparison against reference standard. |
| Residual Epichlorohydrin | GC-FID | Measures trace epichlorohydrin by gas chromatography with flame ionization detection using a polar capillary column and internal standard calibration. |
| Residual D-Glucitol | HPLC-RI | Determines unreacted D-glucitol via HPLC with refractive index detection under isocratic conditions on an amino-bonded column. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to quantify water content based on stoichiometric reaction with Karl Fischer reagent. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator; result expressed as mg KOH/g sample. |
| Hydroxyl Value | Acetylation Titration | Derivatization of hydroxyl groups with acetic anhydride, followed by back-titration of unreacted anhydride with NaOH. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection and external calibration. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection and quantification after acid digestion using inductively coupled plasma mass spectrometry with isotopic dilution or external calibration. |
| Viscosity | Capillary Viscometry | Measures kinematic viscosity at controlled temperature (e.g., 25 C) by timing flow of sample through calibrated capillary tube under gravity. |
| pH (10% aqueous solution) | Potentiometric Measurement | Determines hydrogen ion activity using calibrated pH electrode in a 10% w/w aqueous solution at 25 C. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after charring at 700-800 C and weighing cooled crucible before and after ignition. |
