"Prior Art" Conventionally, regarding the manufacturing method of BEOTP, JP-A-60-13659
0, 63-88193 and the like, 2-oxothiazoline (hereinafter referred to as 2-O) in the presence of an inert solvent and a basic substance.
A method for producing BEOTP by reacting T) with S, O-dialkylphosphorochloride thiolate (hereinafter referred to as BEP) is described and known. Although the former lists organic lithium compounds, inorganic bases and organic bases as basic substances, they are not suitable for industrial practice as specific production examples.
-Butyllithium is only used, which is why metallic sodium is used in the latter case (2
-The reaction of OT and BEP in the vicinity of equimolar ratio improved the applicability in industrial practice to some extent, but metallic sodium is expensive and dangerous to handle, and it melts uniformly in the solvent. However, since it is necessary to disperse it, the operation is complicated, and the productivity is reduced, so that improvement is still required.

In the present invention, an inert solvent, a basic substance, 2-OT
The order of adding BEP and BEP is not particularly limited, and the reaction proceeds in any addition order, but a method of dissolving 2-OT in an inert solvent and then adding a basic substance, and then adding BEP and then performing a reaction is possible. It is desirable from the viewpoint of reaction operation and progress of the reaction, and more desirable effects may be obtained when a small amount of water is present. The basic substance is added as it is, added as a water-soluble or aqueous dispersion, or water is added separately when the basic substance is added. In the present invention, 2
-OT is used in an amount of at least 1.3 mol or more, preferably 1.5 to 5 mol, per mol of BEP. When the amount of 2-OT used is less than the lower limit, for example, when it is equimolar to BEP, the desired BEOTP production rate is about 60%, which is not desirable. On the other hand, in the present invention, the upper limit of the amount of 2-OT used is not set, but an appropriate value is naturally determined in consideration of industrial implementation aspects such as reaction operation and circulation operation. The amount of basic substance used cannot be specified unconditionally due to the difference in reaction conditions, but normally BEP1
The amount is 1.0 to 5.0 mol, preferably 1.0 to 1.2 mol, and similarly, the amounts of the inert solvent and water are usually 300 to 1500 parts by weight and 0 to 40 parts by weight, respectively, relative to 100 parts by weight of BEP. In the reaction of the present invention, a phase transfer catalyst such as benzyltributylammonium chloride, tetrabutylammonium bromide or trioctylammonium chloride, 1,8-diazabicyclo [5,4,0] -7.
When 0.05 to 3.0 mol of any basic catalyst such as -undecene or 1,4-diazabicyclo [2,2,2] octane is added to 1 mol of BEP, the reaction rate may be increased and the production rate of the desired BEOTP may be increased.

The reaction of the present invention cannot be unconditionally defined due to the difference in reaction conditions, but the reaction temperature is -50 ° C to + 40 ° C, preferably -15 ° C to +
It usually finishes in 0.5 to 4 hours, preferably 1 to 2 hours at 15 ° C. The reaction product is generally mixed with water and separated into a solvent phase and an aqueous phase, the solvent phase is washed with water, and then the solvent is distilled off.
BEOTP can be acquired. On the other hand, when 2-OT is used in excess, 2-OT is dissolved in the aqueous phase, so hydrochloric acid is added to the aqueous phase as needed to bring it to an acidic state up to PH4 and extracted with methylene chloride. 2 if methylene chloride is distilled off from the extraction phase
Since -OT can be recovered, this can be circulated for reuse in the reaction. According to the method of the present invention, the desired BEOTP
Can be produced with a high production rate of 85-98%.
