Abstract:
1. A system for manufacturing organopolysiloxane, comprising: N raw material tanks, for respectively storing one of the N raw materials, N being a positive integer; N gauging tanks connected to the N raw material tanks; a first reactor connected to the N gauging tanks; a second reactor connected to the first reactor; a controlling apparatus, connected to the N gauging tanks, the first reactor and the second reactor respectively, for controlling the N gauging tanks to measure the dosage of the N raw materials according to a plurality of processing parameters about the organopolysiloxane, and the measured N raw materials along with a cyclic siloxane monomer being inputted into the first reactor; the first reactor being controlled to carry on ring-opening and re-distribution polymerization equilibrium reaction to the N raw materials and the cyclic siloxane monomer, so as to generate an intermediate product which is transferred into the second reactor; the second reactor being controlled to carry on a decomposition transient catalytic reaction to the intermediate product, and further carry on a devolatilization operation to obtain the organopolysiloxane; and at least one product tanks for storing the organopolysiloxane; wherein the N raw material tanks, the N gauging tanks, the first reactor, the second reactor and the product tanks are arranged in order from high to low, so that the N raw materials, the cyclic siloxane monomer, the intermediate product and the organopolysiloxane are capable of being transferred from high to low due to the gravity effect; wherein the cyclic siloxane monomer has a structure of formula (I): wherein R
