yellow-red liquid, asphyxiating, irritating odor. Strong smoke in the air. The relative density was 1. 678. Melting Point -80 °c. Boiling point 135,6. Flash point 118 °c. Ignition Temperature 234. Refractive index 570. The saturated vapor pressure was 1.33kPa (19 °c). The relative vapor density was 4.7. Soluble in ethanol, benzene, ether, carbon disulfide, carbon tetrachloride, sulfur, iodine, metal chloride, organic compounds of the excellent solvent, water or moisture reaction, decomposition of sulfur, sulfur dioxide and hydrogen chloride and smoke, the emission of irritating and corrosive hydrogen chloride gas. It is very stable at room temperature, but decomposes to sulfur and chlorine at 100 °c and completely decomposes at 300 °c. Can be reduced by the metal to generate chloride and sulfide, saturated with chlorine can generate sulfur dichloride and so on. It can react with metal oxides or metal sulfides to form metal chlorides. Dry sulfur monochloride at room temperature is non-corrosive to copper and iron, and is strongly corrosive to most metals in case of tide.
synthesis method: the sulfur powder is put into the jacket reactor, then the steam is introduced to heat, and a small amount of chlorine is introduced at the same time. After the reaction for 1H, the heating is stopped, and the amount of chlorine is added, maintain the reaction at 50~60 ℃ for 16~20H, after filtration, distillation at 130~141 ℃, determine the relative density of the feed and the content of sulfur monochloride in boiling range is qualified, A sulfur monochloride product was obtained.
low-temperature vulcanizing agent and adhesive for rubber. Unsaturated fatty acids by sulfur monochloride treatment, can be used as pressure lubricant, cottonseed oil, soybean oil, rapeseed oil and other vegetable oils by sulfur monochloride treatment, can be made into a white vulcanized oil glue
belongs to the first class of inorganic acid corrosion articles, risk code number: GB 8.1 class 81032. UNN0.1828; IMDG CODE page 8229, class 8.1. Ceramic tanks, asbestos cement sealing, 60kg net weight per tank. It can also be transported in bulk by tank car. The package shall be marked with "corrosion product. Should be stored in a cool, ventilated warehouse. Keep away from fire and heat source. The temperature of the library is not more than 35 degrees C, and the relative humidity is not more than 80%. Fire-fighting equipment of corresponding variety and quantity shall be provided. The storage area shall have respective leakage emergency treatment equipment and appropriate containment materials. The management system of "five pairs" of extremely toxic substances should be strictly implemented. During transportation, it is necessary to ensure that the container does not leak, collapse, fall or damage. Mixed loading and transportation with acids, alkalis, alcohols, alkali metals and edible chemicals are strictly prohibited. During transport should be protected against exposure to sunlight, rain, high temperature, to prevent collision. During loading and unloading, care should be taken to prevent the ceramic container from breaking. When there is a fire, it can be suppressed by sand and dry powder, but it should not be used with water. Fire-fighting personnel must wear filter-type gas masks (full face masks) or isolated respirators, and full-body fire-fighting and virus-proof clothing to put out fire in the upward wind direction. Toxicity and protection: LC50150ppm (mouse, inhalation). This product is non-flammable, highly toxic, strong corrosive, strong irritation, can cause human burns. Has a asphyxiating odor, strong irritation of the eye and upper respiratory mucosa, and can cause severe skin burns. A small number of serious poisoning can cause pulmonary edema. The vapor of sulfur monochloride causes tears. Contact with water will be decomposed to produce hydrogen chloride, the skin and mucous membranes have strong irritation. The maximum allowable concentration in the environment is 6mg/m3. After skin or eye contact, apply a large amount of flowing water or saline to rinse for more than 15min. In case of accidental inhalation, the patient should be separated from the site to a place with fresh air, Keep airway unobstructed. Such as Dyspnea, to the delivery of oxygen. If breathing stops, perform artificial respiration immediately. The patient visited hospital. After eating, should immediately rinse with water, to drink milk or egg white. The patient visited hospital. The production workshop and equipment should be closed, and the workshop should be well ventilated. The operator should wear gas masks (full face mask), rubber acid and alkali-resistant clothing and rubber acid and alkali-resistant gloves to protect the respiratory organs and skin. Smoking, eating and drinking are prohibited at work. After completion of work, shower and dressing.
