Definitions
- the invention relates to a process for the preparation of siloxane-branched SiOC-linked polyether siloxanes. Furthermore, the invention also relates to preparations consisting of a SiOC-linked branched silicone polyether together with a polyetherol and a polyetherol end-capped by acetyl groups. Furthermore, the invention relates to the use of these siloxane-branched SiOC-linked polyether siloxanes as defoamers, as foam stabilizers, wetting agents, coating and leveling additives and as Dismulgatoren.
- Older processes for the preparation of branched SiOC-linked polyethersiloxanes are based essentially on chlorosilane chemistry (methyltrichlorosilane and dimethyldichlorosilane) and provide for the attachment of the polyether substituents by reacting the SiCI-group-carrying siloxanes with the respective polyetherol in the presence of suitable auxiliary bases in order to obtain the Linkage reaction liberated hydrochloric acid in the form of salts to bind.
- the simple chlorosilanes originating directly from the Müller-Rochow synthesis directly synthesis
- the storage and handling of these corrosive educts on a production scale raises many problems, for example questions about material resistance, exhaust gas, waste, etc. What makes such legacy processes increasingly unattractive from today's perspective.
- EP17156421.4, EP 17169876.4 are aimed at mixtures of cyclic-branched D / T-type siloxanes and teach their further processing into functionalized branched siloxanes and / or branched silicone oils.
- the further processing disclosed therein is carried out by acid equilibration of the D / T-structured siloxanes with silanes and / or siloxanes.
- branched SiOC-linked polyethersiloxanes in the siloxane moiety are accessible, for example, by equilibrating mixtures of cyclic branched D / T-type siloxanes with diethoxydimethylsilane and then carrying out, for example, the metal-catalyzed replacement of the ethoxy substituents by polyalkyleneoxy radicals in the context of transesterification.
- diethoxydimethylsilane is a costly modification agent, limiting its widespread use.
- the technical problem to be solved is to find a simple and at the same time economical process that allows the production of branched in siloxane SiOC-linked polyether siloxanes.
- educts such as chlorosilanes / chlorosiloxanes and intermediates such as the mineral acid alkylhalosiloxanes, for example the well-known chlorosiloxanyl sulfates, should be deliberately avoided.
- the branched in siloxane SiOC-linked polyether siloxanes should have a good performance quality.
- sulfo-bridged siloxanes are reactive species which, for example, can undergo undesired secondary reactions upon storage and depending on the temperature and any moisture that may be introduced into the system with liberation of sulfuric acid.
- Borisov and Sviridova describe the opening of cyclic dimethylsiloxanes with acetic anhydride in the presence of catalytic amounts of iron (III) chloride to short-chain ⁇ , ⁇ -acetoxysiloxanes (SN Borisov, NG Sviridova, J. Organomet Chem 1, 1968, 27-33). , Lewis et al.
- US Pat. No. 3,346,610 also discloses access to acetoxy group-bearing short-chain siloxanes which is based on metal halide-induced acetoxy modification of strained cyclic siloxanes by reacting them with acetoxy group-containing silicone compounds.
- a variety of Friedel-Crafts active metal halides act as a catalyst, with zinc chloride being preferred.
- a particular objective of US 3346610 is the acetoxy modification of strained diorganosiloxane cycles, with deliberate avoidance of equilibration events.
- the prior art thus relates to work which provide the opening of cyclic siloxanes - here sometimes strained cyclosiloxanes - with reactants containing acyloxy groups and whose objective is to obtain defined linear short-chain and siloxane species which are still to be separated by fractional distillation.
- the molecular mass-defined, chain-pure acetoxy-modified siloxane compounds synthesized in this way are not suitable for the preparation of organomodified siloxanes, in particular polyethersiloxanes, which are used in demanding technical applications, for example in PU foam stabilization or in the defoaming of fuels, etc. to take.
- Agents that effectively address such a field of application are always characterized by a broad oligomer distribution comprising high, medium and low molecular weights, since the oligomers contained in them very often differentiated surfactant depending on their molecular weight and thus their diffusion behavior Tasks in different time windows of the respective process are attributable.
- Acyloxyorganopolysiloxanes and in particular organosiloxanes with terminal acyloxy groups are known as starting materials for subsequent reactions.
- the acyloxy groups can be hydrolyzed in a diorganosiloxane, whereupon the hydrolyzate can be dehydrated and the dehydrated hydrolyzate polymerized to form a flowable diorganopolysiloxane.
- These flowable polysiloxanes are useful as starting materials for the preparation of viscous oils and rubbers which can be cured to silicone elastomers.
- Organosiloxanes provided with terminal acyloxy groups can be obtained, for example, by reacting an alkylsiloxane and an organic acid and / or anhydride thereof in the presence of sulfuric acid as a catalyst. Such a process is described in US Pat. No. 2,910,496 (Bailey et al.). Although in principle organosiloxanes having terminal acyloxy groups are also obtained by this process, the disadvantage of the process is that the reaction product consists of a mixture of acyloxy-containing siloxanes and acyl-containing silanes of different composition.
- alkylsiloxane copolymers composed of M, D and T units are cleaved by the process into trimethylacyloxysilane, di-acyloxydimethylsiloxane and methyltriacacylsilane.
- octamethylcyclotetrasiloxane with acetic anhydride and acetic acid
- acetic anhydride after neutralization of the sulfuric acid used as a catalyst, separation of the salts and removal of water, residual acetic acid and acetic anhydride
- Bailey obtains a complex mixture and in no case an equilibrate, which he subjects to fractional distillation (see Example) , ibid.).
- the material identity of the resulting fractions II and IV remains unclear, so that it is difficult thereafter to obtain defined products, or to separate them in high yields from the mixture.
- branched SiOC-linked polyethersiloxanes can be prepared starting from cyclic-branched siloxanes of the D / T type in the siloxane moiety by reacting

- both mixtures of cyclic branched D / T type siloxanes which consist exclusively of siloxanes having D and T units and their total fraction of the D present in the siloxane matrix can be determined by 29 Si NMR spectroscopy and T units which have Si-alkoxy and / or SiOH groups, less than 2 mol%, preferably less than 1 mol%, and furthermore advantageously at least 5% by weight of siloxane cycles, preferably octamethylcyclotetrasiloxane (D 4 ) , Dekamethylcyclopentasiloxan (Ds) and / or mixtures thereof,

- another object and another preferred embodiment of this invention is the salt-free exchange of acetoxy groups attached to branched siloxane moieties by polyetheroxy groups by subjecting the branched siloxane bearing trifluoromethanesulfonic acid acetoxy group optionally in the presence of bases in a solvent together with the polyetherol Stirring brings to a reaction and then in the course of a distillation, the resulting and optionally present in the system already present acetic acid and residues used Acetanhydrids optionally together with portions of the solvent used.
- toluene is most preferred.
- the use of toluene therefore corresponds to a preferred embodiment of the invention.
- the boiling points of toluene and acetic acid are with 1 10.6 and 1 18.5 ° C and the boiling point of the binary Azeotrope at 105.4 ° C indicated.
- the azeotrope has a composition of 72 weight percent toluene and 28 weight percent acetic acid (Source: Handbook of Chemistry and Physics, 58th Edition, page D2, CRC Press (1977-1978), West Palm Beach).
- the mixture obtained according to the invention after the second step comprising a siloxane-branched, acetoxy-bearing, equilibrated siloxane and optionally unreacted acetic anhydride and the catalyst acid therein, are reacted with a polyetherol in the third step without adding a base, then depending on the selected stoichiometry of the reactants, the temperature and the reaction time, in addition to the SiOC-linked branched silicone polyether also changing proportions of an acetyl group end-capped polyether. This corresponds to a preferred embodiment of the invention.
- an auxiliary base such as, for example, sodium bicarbonate is introduced into the polyetherol and then charged with the mixture resulting from the second step comprising an siloxane-branched, equilibrated siloxane containing acetoxy groups in addition to unreacted acetic anhydride and the catalyst acid present therein, the early neutralization of the Acid to that no esterification of hydroxy-functional polyether observed (Example 4).
- the replacement of the siloxane-bound acetoxy groups in the presence of a base in particular in the presence of sodium bicarbonate, ammonia or an organic amine.
- the preparation obtained according to the invention consists of a SiOC-linked branched silicone polyether together with a polyetherol and an acetyl-terminated polyetherol.
- Such reduced hydroxy functionality formulations may be of interest in particular applications and are also an object of the present invention.

- trifluoromethanesulfonic acid is preferably present in concentrations of from 0.05 to 0.2 percent by weight (% by weight), more preferably in concentrations of from 0.07 to 0.15 percent by weight (% by weight), based on the total mass of the reaction mixture used. This corresponds to a preferred embodiment of the invention.
- branched acetoxysiloxanes can be produced very rapidly and advantageously by catalysing the cyclic-branched D / T-type trifluoromethanesulfonic acid siloxanes catalyzed with acetic anhydride, optionally in admixture with simple siloxane cycles with the addition of acetic acid Reacting acetoxy-bearing, branched siloxanes, which corresponds to a very particularly preferred embodiment of the invention.

- this total cycle content should preferably be less than 8 Percent by weight, preferably less than 7 percent by weight, of the branched isopropoxysiloxane siloxane matrix.
- anhydrous ferric chloride, Filtrol® (strong acid bleaching earth) and concentrated sulfuric acid as catalysts address only the first step of the process of the invention, while trifluoromethanesulfonic acid as catalyst densifies the first and second steps advantageously into one process step, that is, both the acetylation the cyclic-branched D / T-type siloxanes as well as the equilibration of the acetoxysiloxane catalyzes.
