What is Paraformaldehyde Solution?

Paraformaldehyde Solution (IUPAC named Polyoxymethylene, POM) is a polymer of formaldehyde (high molecular weight polyoxymethylene), with a general structural length of eight to one hundred units. Long-chain paraformaldehyde is frequently utilized in heat-resistant plastics, additionally known as polyoxymethylene plastics (POE, Derlin produced by DuPont). Paraformaldehyde breaks down quickly and also launches somewhat odorous formaldehyde.

Paraformaldehyde Solution Uses

  1. Paraformaldehyde Solution is used as a raw material for organic chemicals and synthetic resins, and as a pharmaceutical fumigant.
  2. Paraformaldehyde Solution is solid formaldehyde with high formaldehyde content in solid granular form, which is convenient for storage and transportation. It can turn into formaldehyde vapor at higher temperature, which is easy to replace high-concentration formaldehyde to participate in various reactions, which is beneficial to chemical synthesis such as chemical industry, pharmacy and other industrial applications, especially in the synthesis that requires the use of anhydrous formaldehyde as raw material ,Wide range of uses. Mainly in the following aspects (1) Pesticides: synthesis of acetochlor, butachlor and glyphosate, etc.; (2) coatings: synthesis of high-grade automotive paints; (3) resins: synthesis of urea-formaldehyde resins, phenolic resins, polyacetal resin, melamine resin, ion exchange resin, etc. and various adhesives; (4) papermaking: synthetic paper strengthening agent; (5) foundry: sand casting release agent, synthetic foundry adhesive; (6) aquaculture: smoked Steam disinfectant. (7) Organic raw materials: used for the preparation of pentaerythritol, trimethylolpropane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethacrylamide, alkylphenol, methyl vinyl ketone, etc. (8) Others: medicine and disinfection.
  3. Paraformaldehyde Solution is used in the pharmaceutical industry and also as a sterilant.

Preparation of Paraformaldehyde Solution

Concentrate the aqueous solution containing 37% of formaldehyde in vacuo at 65°C to obtain a concentrated aqueous solution of paraformaldehyde containing 80% of formaldehyde, add the suspension at a concentration of 1.5%, and the manufacturing method of the suspension is to disperse the magnesium oxide fine powder into In methanol, obtain a methanol suspension with a magnesium oxide concentration of 50 ppm, then add it to an extruder to obtain 2-5mm particles, add the particles to a dryer, and dry for 60 minutes to make a solid content of 80% The paraformaldehyde can be made into 92% paraformaldehyde after drying for 120 minutes, and its output is 400kg/hr.

Paraformaldehyde Solution Health Hazards

Routes of immersion: inhalation, ingestion
Health Hazards: Respiratory burns, eye burns, skin irritation.
Acute: Inhalation can severely irritate the respiratory tract, causing inflammation of the nose or throat, bronchi, and lungs.
Chronic: Ingestion can cause severe irritation and inflammation of the mouth, pharynx and stomach, and can cause cancer.
Skin Contact: Pain, rash may occur.
Eye Contact: Pain may be severe pain, tearing, blurred vision, etc.
Inhalation: Pain or severe pain, loss of smell, digestive system confusion, difficulty breathing, lung congestion, asthma, etc.
Ingestion: Burns, nausea, vomiting, diarrhea, stomach pain, dizziness, convulsions, and damage to kidneys and liver.
Hazards to the natural environment: Dust mixed with air can burn or explode. It can be decomposed in air, light, humidity, heating or storage above room temperature. The released gas is toxic and corrosive, flammable and explosive. In contact with water, it is easily dissolved into an aqueous formaldehyde solution, which is released into the soil and can be decomposed by organisms.
Accidental release measures:
Isolate the leaked pollution area, set up warning signs around it, and cut off the fire source. It is recommended that emergency personnel wear gas masks and general fire protection clothing. Use non-sparking tools to collect in dry, clean, covered containers and transport to waste disposal site. In case of large spill, wet with water and contain for recovery.
Protective measures:
Respiratory protection: Wear a dust mask. Wear a gas mask if necessary.
Eye Protection: Wear safety glasses.
Protective clothing: Wear appropriate protective clothing.
Hand Protection: Wear protective gloves.
Others: Smoking, eating and also drinking are restricted at the work environment.After work, shower and change. Pay attention to personal hygiene.
first-aid
Skin Contact: Remove contaminated clothing and rinse thoroughly with soap and water.
Eye Contact: Immediately lift the eyelids and rinse with running water or saline for at least 15 minutes. seek medical attention.
Inhalation: Get out of the fresh air immediately. Keep the airway clear. Give oxygen if breathing is difficult. Once breathing stops, begin CPR immediately. seek medical attention.
Ingestion: If swallowed by mistake, drink plenty of warm water, induce vomiting, and seek medical attention.
Extinguishing methods: water mist, foam, carbon dioxide, dry powder, sand.
