Typical application editor

Used as a viscosity modifier, in natural rubber latex concentrate adding dry gum 0.15% of hydroxylamine hydrochloride, plug in the rubber molecule of the aldehyde. The longer and other rubber molecular aldehyde condensation reaction occurs, can avoid crosslinking lead to Mooney viscosity increasing, constant viscosity of latex. Also used as a short-term terminator for synthetic rubber.

Nature and stability editor

1 strong moisture absorption, moisture is higher than 151 degrees Celsius decomposition. At 17 C, 100g dissolved in water 83.8g

2 this product is highly toxic, irritating to the skin. Production equipment should be closed to prevent running, run, drip, leak, the operator should wear protective equipment. Splashing and the skin can be a large amount of water flush

Storage method editor

1 should be stored in a cool, ventilated, dry warehouse.

2. This product adopts inner lining plastic bag, middle backing paper bag, outer polyethylene bags, then barrel or drum packaging, each bag 25kg. This product is easy to absorb moisture, heating depth of decomposition, so it needs to be sealed and stored in a dry place, moisture, heat. According to the provisions of storage of toxic substances.

Synthesis method editor

1 sodium nitrite synthesis method (chemical method) to add water to the reaction vessel, stir to add sodium nitrite, sub sub sodium sulfate, and then sulfuric acid. The material is fed into the hydrolysis acidification reactor, adding acetone, then alkali neutralization, neutralizing liquid will be distilled to acetoxime. The acetone oxime hydrochloride and adding salt into the reaction kettle, generating hydroxylamine hydrochloride and acetone. By using acetone recovery; hydroxylamine hydrochloride concentration and cooling crystallization, centrifugal separation and drying to obtain the product. Material consumption quota: sodium nitrite (95%) 1970kg/t, sodium nitrite (SO2 64%) 5418kg/t, acetone (98%) 1175kg/t. The 2 method of nitromethane nitromethane and hydrochloric acid, the effect of water to produce hydroxylamine hydrochloride. According to HGB3044-76, the product of hydroxylamine hydrochloride is a white crystalline, two grade content is more than 98.5, three grade content is more than 97%. Raw material consumption quota: nitro methane 1200kg/t, hydrochloric acid (30%) 1500kg/t

2 or by nitromethane and hydrochloric acid, the effect of water to produce hydroxylamine hydrochloride

3. Sodium nitrite water dissolved and cooled to 0 DEG C, adding sodium bisulfite and 35% ~ 40% dilute sulfuric acid solution ph=2, adding acetone to the temperature rise to 35 DEG C, stop stirring, temperature rise to 70 DEG C for 3 hours, down to 30 DEG C and sodium hydroxide solution to pH value 7 ~ 8. The acetone is heated to evaporate, add hydrochloric acid, maintain the temperature 55 ~ 60 degrees C, thermal insulation 12h, and then concentrate. Slightly cold after decolorization, filtration, and then concentrated, cooling, crystallization, then get the finished product. Refined
