Embodiment 1

[0085] Preparation of 3-(methylpolyethylene glycol)propyltrimethoxysilane

[0086] For the continuous production of 3-(methylpolyethylene glycol) propyltrimethoxysilane (Dynasylan 4140) The used device basically consists of a feed storage vessel, an HPLC pump, a regulating, measuring and metering unit, a T-mixer, four parallel, replaceable and filler-filled stainless steel prereactors (diameter All 10mm, length 50mm, stainless steel pellets with an average diameter of 1.5mm as filler), stainless steel monolithic block reactor (for this see Figure 5 ), temperature regulator, constant pressure regulating valve, with N 2 Operating stripper and compound conduits in the plant for supplying feed between the aforementioned plant parts and the product outlet, recovery outlet and waste gas outlet. In addition, temperature adjustments regarding the heating system and cooling system are provided for pre-reactors and block reactors.

Embodiment 2

[0089] For the preparation of 3-(methylethylene glycol)propyltrimethoxysilane (Dynasylan 4140), using the device according to Example 1.

[0090] First, polyether olefins (ZALP 500, Goldschmidt) and Pt(0) Complex catalyst (CPC072, Degussa) solution, and it was mixed, and in a T-type mixer with trimethoxysilane (TMOS, Degussa AG) mixed with olefin: TMOS = 1: 0.85 molar ratio, and supplied to in the reactor system. Wherein the pressure is 25±10 bar. When the device is started, it should strive to be as free as possible of H 2 O's device status. In addition, the apparatus was flushed with the feed mixture for 2 hours before the temperature in the reactor was raised. The temperature of the reactor was adjusted forward to 130° C. at a total throughput of 10 kg / h and operated continuously for 10 days. Samples were drawn periodically after the reactor for GC-WLD testing. The conversion, based on the olefin, was on average 97%, and the selectivity, based on the target product,...

Abstract

The present invention relates to a device, a reactor and a method for implementing continuously the industrial reaction as follows, to make the alkene A replaced by alpha, beta-unsaturated fluorin and HSi-compound B under the state of existing activator C and optional adjuvant. The device is based on at least that as follows: a material feeding chief pipe (3) for component A (1) and B (2), at least one multi-element reactor (5) which comprises at least one replaceable front reactor (5.1) and at least one other connecting to at least two reactor units of a reactor unit (5.3) locating the downstream of the front reactor, and a outcome rear processing (8).

Description

technical field [0001] The present invention relates to a novel reactor and apparatus and a related process for the continuous industrial production of polyetheralkylalkoxysilanes by allowing α,β-unsaturated aliphatic polyethers Compounds react with HSi-compounds.
