| Physical and Chemical Properties | Pure white needle-like crystal, odorless, m. P. 99.5 ℃ (decomposition) (104~105 ℃). The vapor pressure was 400 x 10-6Pa. Soluble in acetone, chloroform; Slightly soluble in ethanol, benzene; Difficult to dissolve in ether, carbon tetrachloride; 25 ° C in water solubility of 0.12%, slightly increased solubility in warm water. The aqueous solution is easy to decompose, and the temperature is above 45 ° C. The decomposition is accelerated, which affects the effect of the medicament; It is easy to decompose in case of strong acid and strong alkali. |
| Use | Used as a fungicide |

| toxicity | acute oral LD50 in rats is 500~650 mg/kg(550~710 mg/kg), and acute oral LD50400mg in mice/kg. Acute percutaneous LD502360 in rabbits ~ 2600 mg/kg. It has a stimulating effect on the eyes and skin. The 2-year feeding test had no effect at a dose of 10mg/kg per day. Animal experiments showed no carcinogenic, teratogenic and mutagenic effects. Carp LC5010mg/L (48h), mallard via oral LD50473mg/kg, safe for bees. |
| use | broad spectrum pesticide. The nematicide with fumigation effect decomposes methyl isothiocyanate, formaldehyde and hydrogen sulfide in the soil, and has a killing effect on nodule nematodes, stem nematodes, and isothecia. In addition, it has insecticidal, bactericidal and weeding effects, so it can also treat soil fungi, underground pests and Chenopodium weeds, such as potato Rhizoctonia, soil-bar phosphoptera insects, kowtow insects, and larvae of May tortoise shells. Using 98% particle agent 750~900g/100m2 sandy soil and 900~1050g/100m2 clay as soil treatment, spreading or furrow application can prevent vegetable and peanut nematode disease. 75% wettable powder 1125g/100 m2 can be used to control potato root nematode disease. Soil fumigant, methyl thioisothiocyanate nematicide, and also treats fungi, underground pests and weeds, also known as fast extinction. The product is decomposed in the soil to form methylamine methyl dithiocarbamate, and further to form methyl isothiocyanate. It can effectively control nematodes and soil fungi, such as quencher, Rhizoctonia, Fusarium, etc., and can also inhibit the growth of many weeds. Mianlong has a good control effect on cotton yellow wilt. Used as a fungicide |
| Production method | It is obtained by the reaction of monomethylamine with carbon disulfide and formaldehyde. Raw material consumption quota: 530kg/t carbon disulfide, 1170kg/t methylamine and 1120kg/t formaldehyde. Mianlong is synthesized from methylamine, formaldehyde and carbon disulfide. |
