HOW TO SODIUM ACITATE IN BYE LAXMI ENTERPRISE.

What is made Sodium acetate (anhydrous) — NaC₂H₃O₂ (molar mass ≈ 82.0338 g·mol⁻¹). Typical forms: anhydrous and trihydrate (common lab form). Two simple chemical routes (balanced) From sodium hydroxide (neutralization) CH₃COOH + NaOH → CH₃COONa + H₂O From sodium bicarbonate (gentler, gas evolution) CH₃COOH + NaHCO₃ → CH₃COONa + CO₂↑ + H₂O Both give sodium acetate; choose NaOH for a water-salt-free approach (but exothermic), or NaHCO₃ if you want a milder reaction (CO₂ evolved — useful in lab demos). Lab-scale example calculations (careful stoichiometry) Molar masses used (rounded): NaC₂H₃O₂ = 82.0338 g·mol⁻¹ CH₃COOH = 60.0520 g·mol⁻¹ NaOH = 39.9971 g·mol⁻¹ NaHCO₃ = 84.0066 g·mol⁻¹ Target: prepare 100.0 g anhydrous sodium acetate Required moles = 100.0 ÷ 82.0338 = 1.2190 mol If using NaOH: CH₃COOH needed = 1.2190 × 60.0520 = 73.20 g NaOH needed = 1.2190 × 39.9971 = 48.76 g If using NaHCO₃: CH₃COOH needed = 73.20 g (same) NaHCO₃ needed = 1.2190 × 84.0066 = 102.40 g (You may instead measure by volume when using glacial acetic acid — convert by density: glacial acetic acid ≈ 1.049 g·mL⁻¹.) For a 1.000 mol batch (useful reference): Sodium acetate yield = 82.0338 g React with 60.0520 g acetic acid and 39.9971 g NaOH (or 84.0066 g NaHCO₃). Practical lab procedure (small batch using NaHCO₃ — recommended for safety) Materials: glacial acetic acid (or 10%–20% v/v solution), sodium bicarbonate, distilled water, ice bath, stirrer, filter paper, oven or vacuum oven. Dissolve the calculated mass of NaHCO₃ in ~2–4× the final mass of distilled water (to form a clear suspension). Place the bicarbonate solution in an ice bath and begin stirring. Slowly add the measured acetic acid to the bicarbonate solution dropwise — CO₂ will evolve. Add with good stirring and keep temperature controlled (CO₂ evolution is mildly exothermic). After addition, stir 10–20 min to ensure reaction completes. You should have a clear solution once CO₂ evolution subsides. Filter if there are insolubles. Concentrate the solution under reduced pressure or by gentle heating to induce crystallization (cool to 0–5 °C to maximize yield of trihydrate/anhydrate depending on temperature). Collect crystals by filtration or centrifuge. Sodium Acetate Sodium Acetate Anhydrous Sodium Acetate Trihydrate NaC₂H₃O₂ Sodium Acetate Powder High Purity Sodium Acetate Industrial Sodium Acetate Dry crystals: For trihydrate: store as-is (many labs use trihydrate). For anhydrous: dry in an oven or vacuum oven at 110–120 °C (or per validated drying profile) until constant weight. Use vacuum drying if possible to prevent decomposition. Mill/sieve to required particle size and pack. Notes: If using NaOH instead, add NaOH solution into acetic acid (or add acetic acid to NaOH slowly) with cooling. Adding base into acid causes a vigorous exotherm if done too fast — control addition rate and temperature. Industrial / plant-scale overview Neutralization reactor (jacketed) — control pH to ~7.0 (1:1 mole basis). Add base slowly with cooling and pH monitoring. Clarification / filtration — remove insoluble impurities. Evaporation/crystallization — controlled evaporation and seeded crystallization to target crystal form (anhydrous vs trihydrate). Centrifuge / filter press — separate crystals. Drying — tray or fluid-bed drier or vacuum drier to required residual moisture. Milling & sieving — particle size control. Packaging — bagging or bulk. QA sampling for each lot. Typical product specifications (example template — replace values with lab data) Product: Sodium acetate (NaC₂H₃O₂) — anhydrous / trihydrate (specify) Assay (as NaC₂H₃O₂): ≥ 99.0 % (example) Appearance: White crystalline powder Moisture (if anhydrous): ≤ 0.5 % w/w pH (1% solution): ~8.0–9.0 (depends on form) Chloride (Cl⁻): ≤ 0.01 % Sulfate (SO₄²⁻): ≤ 0.01 % Iron (Fe): ≤ 5 ppm Residue on ignition / carbonate: ≤ specified limit Typical particle size: 100% < 2 mm (customizable) Packaging: 25 kg / 50 kg kraft bags, jumbo bag, bulk (Validate each parameter with lab analysis and list detection methods on COA.) Quality control & tests Assay by titration or ion chromatography. Moisture by Karl Fischer or loss on drying. Impurities by ICP (metals), ion chromatography (halides, sulfate). pH of 1% aqueous solution. Crystallinity/water of hydration by TGA / DSC. Safety, handling & storage Acetic acid (glacial) is corrosive; use gloves, goggles, fume hood. NaOH is caustic — handle with care (if used). Add slowly to avoid exotherm. CO₂ evolution with bicarbonate route — provide ventilation. SDS & COA: always supply to customers (you already use these CTAs). Storage: keep dry in sealed containers. Hygroscopic under humid conditions (trihydrate forms). Avoid contamination. Typical uses (so you can place on product page) Buffering agent (laboratory & biochemical) Textile and dyeing auxiliaries Concrete admixtures / accelerators (in some formulations) Food industry (as sodium acetate trihydrate: preservative E262) — note: food-grade production requires GMP and appropriate purity/certification Hand warmers / heating pads (heat released during crystallization of supersaturated solution) Corrosion inhibitor in certain packaging environments Troubleshooting & tips If product contains excess sodium carbonate — reduce exposure to CO₂ or neutralize more precisely.
