Uses

Butachlor is a pre-emergent chloroacetanalide herbicide. Butachlor is commonly used for weed control in rice as well as cotton, maize, wheat and other crops.

Specification

The IUPAC name of Butachlor is N-(butoxymethyl)-2-chloro-N-(2,6-diethylphenyl)acetamide. With the CAS registry number 23184-66-9, it is also named as Acetamide, N-(butoxymethyl)-2-chloro-N-(2,6-diethylphenyl)-. The product's categories are Agro-Chemicals; Herbicide; A-BAlphabetic; BI - BZ; Pesticides & Metabolites. It is pale yellow oily liquid which is soluble in acetone, ethanol, methanol, benzene and other organic solvents. It is toxic. When buring it will produce toxic nitrogen oxide and chloridate gas. So the storage environment should be well- ventilated, low-temperature and dry. Keep Butachlor separate from raw materials of food.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 5.24; (2)# of Rule of 5 Violations: 1; (3)ACD/LogD (pH 5.5): 5; (4)ACD/LogD (pH 7.4): 5; (5)ACD/BCF (pH 5.5): 6636; (6)ACD/BCF (pH 7.4): 6636; (7)ACD/KOC (pH 5.5): 18936; (8)ACD/KOC (pH 7.4): 18937; (9)#H bond acceptors: 3; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 9; (12)Index of Refraction: 1.536; (13)Molar Refractivity: 94.261 cm³; (14)Molar Volume: 302.221 cm³; (15)Polarizability: 37.368×10^-24 cm³; (16)Surface Tension: 40.077 dyne/cm; (17)Enthalpy of Vaporization: 70.899 kJ/mol; (18)Vapour Pressure: 0 mmHg at 25°C; (19)Rotatable Bond Count: 9; (20)Exact Mass: 311.165207; (21)MonoIsotopic Mass: 311.165207; (22)Topological Polar Surface Area: 29.5; (23)Heavy Atom Count: 21; (24)Complexity: 287.

Preparation of Butachlor: First, we can get N-methylene 2,6-diethylaniline by paraformaldehyde and DEA. And then, reacting with chloroacetyl chloride to get N-(2,6-diethyl-phenyl)-N-chloromethyl chloroacetamide. At last, reacting with n-butanol to get the product.

Uses of Butachlor: It is a kind of selective preemergenceherbicide which is used for the control of barnyard grass in rice.
