| MSDS | 1. this product has strong irritation to mucous membrane, upper respiratory tract, eyes and skin. After inhalation, it can be fatal due to spasm, inflammation, edema, chemical pneumonia or pulmonary edema of the larynx and bronchus. After contact, there are burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Can cause burns. In case of open flame, high heat or contact with oxidant, there is a risk of combustion and explosion. The toxic nitrogen oxide flue gas is released by thermal decomposition. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion. 2. Wear a gas mask when protective measures may contact its vapor. When rescuing or escaping in an emergency, it is recommended to wear a self-contained respirator. Wear chemical safety protective glasses. Wear overalls (made of anti-corrosion materials). Wear rubber gloves. Smoking, eating and drinking are prohibited at the work site. After work, shower and change. Maintain good hygiene. 3. First aid measures If there is skin contact with 1, 3-propanediamine, remove the contaminated clothing and immediately rinse with water for at least 15 minutes. If there are burns, seek medical treatment. If there is contact with 1, 3-propanediamine, immediately lift the eyelids and rinse with flowing water or normal saline for at least 15 minutes. Medical treatment. If inhaled or ingested 1, 3-propanediamine: quickly leave the scene to fresh air. Keep your respiratory tract unobstructed, rinse your mouth immediately and drink milk or egg white. Give oxygen when breathing is difficult. When breathing stops, artificial respiration is performed immediately. Medical treatment. |
| use | solvent. Purifying agent. Organic synthesis intermediate, starting material for KAPA preparation, strong base for molecular terminal isomerization. 1, 3-propanediamine can be used in medicine, emulsifier, antioxidant, rubber vulcanizing agent, etc., and can also be used in the synthesis of medicine and pesticides. It is an auxiliary raw material for papermaking, textile, and leather industries. It is also used for epoxy resin Curing agent synthesis. |
