| Abstract: | A new experimental equipment was provided, based on which a new process for synthesis of 3-isocyanatopropyltriethoxysilane was developed. The product was obtained with good yield and purity. Process was characterized as simple device and procedure, environment-friendly, and easy to operate.Product was obtained under high vacuum and low temperature, which reduced the polymerization of the product.DMF can be recovery, the total cost and waste was reduced.It was definitely a green process. |
