 Morfothion (CAS NO.144-41-2) has a strong absorption, high efficiency, low toxicity and other characteristics. It is mainly used for prevention and control aphid, cabbage aphid, cotton red spider, thrips and other pests of cotton.

With chloroacetyl morpholine and O, O-dimethyl dithiophosphate sodium derived from the direct condensation. Process conditions: charge ratio of the O, O-dimethyl dithiophosphate sodium: chlorine acetyl morpholine = 1.05-1.10 (molar ratio). Adding O, O-dimethyl-2 sodium to reaction bottles, ice bath cooling, when the material temperature dropped to below -8 °C, combined with morpholine (30% or more), keeping the temperature below -5 °C. Drops of chlorine chloride until the pH value is close to 7.0, immediately dropping liquid caustic soda. Chloroacetyl chloride drops exhausted at -8 °C stirring reaction 1h. Then add benzene, at 50-60 °C stirring reaction 1h, cooling, put it aside, separate the benzene layer, vacuum distillation derived mao fruit. Preparation of 25% of the emulsion or powder.

Poison by ingestion and skin contact. A cholinesterase inhibitor. When heated to decomposition it emits very toxic fumes of PO_x, SO_x, and NO_x. See also PARATHION.

 Morfothion (CAS NO.144-41-2) is also called 4-(Mercaptoacetyl)morpholine O,O-dimethyl phosphorodithioate ;BRN 0995667 ; Caswell No. 371 ; Dimethyl S-(morpholinocarbonylmethyl) phosphorothiolothionate ; Dithiophosphate de O,O-dimethyle et de S-((morpholinocarbonyle)-methyle) ; EPA Pesticide Chemical Code 371100 ; Ekatin F ; Morfothion [Dutch] ; Morpholine, 4-(mercaptoacetyl)-, S-ester with O,O-dimethyl phosphorodithioate ; Morphotox ; O,O-Dimethyl S-(morpholinocarbamoylmethyl) dithiophosphate ; O,O-Dimetil-S-((morfolino-carbonil)-metil)-ditiofosfato [Italian] ; Phosphorodithioic acid, O,O-dimethyl S-(morpholinocarbonylmethyl) ester ; Systicide . Morfothion (CAS NO.144-41-2) is white crystal. It can be dissolved in most organic solvents. Morfothion (CAS NO.144-41-2) is high toxic. It will produce toxic phosphorus oxide, sulfur dioxide, nitrogen oxide gas by heat. So the storage environment should be ventilate, low-temperature and dry. Keep Morfothion (CAS NO.144-41-2) separate from raw materials of food.
