权利人:HENKEL AG & CO KGAA
摘要:The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions.

摘要:The synthesis of certain polyester diols (PEDs) is disclosed. This application also discloses the purification and polymerization kinetics of lipid based PEDs. Molecular weight and distribution controls were achieved by initial and induced stoichiometric imbalance and optimization of the purification protocol. Thermal degradation and thermal transition behavior of the PEDs were also investigated by TGA and DSC.

标 题 :Etheramines prepared from a mixture of two or more multifunctional alcohol initiators, and their use as curatives or intermediates for polymer synthesis

摘要:Implementations described herein generally relate to etheramine mixtures formed from a mixture of two or more multifunctional alcohol initiators, processes for the etheramine mixtures production, and its use as a curing agent or as a raw material in the synthesis of polymers. In one implementation, the process comprises mixing a polyol initiator having a melting point greater than a processing temperature and a polyol initiator having a melting point less than the processing temperature to form a polyol initiator mixture having a melting point less than the processing temperature, charging the polyol initiator mixture to an alkoxylation reaction zone, contacting the polyol initiator mixture with an alkylene oxide in the alkoxylation reaction zone to provide a mixture of alkoxylated precursor polyols and charging the mixture of alkoxylated precursor polyols to a reductive amination zone and reductively aminating the mixture of alkoxylated precursor polyols to form the etheramine mixture.

权利人:COVESTRO DEUTSCHLAND AG
摘要:The invention relates to a method according to claim 1 for the commercial implementation of a pyrolysis, and to pyrolysis devices for the pyrolysis of pyrolysis stock used in this method. The pyrolysis stock contains a polymeric compound having at least one structural polyurethane unit of the formula (I), wherein Q is a hydrocarbon group with 2 to 8 carbon atoms, preferably 3 to 8 carbon atoms, and n represents a number from 2 to 4, most preferably 2, and -* represents a covalent bond to the polymer backbone. The method and the pyrolysis device according to the invention allow, even with higher compounds of pyrolysis stock an amount of pyrolysis product to be obtained that contains cleavage products which can be reused for the synthesis of polyurethane-containing material.

摘要:An unsaturated (meth) acrylic compound of formula: (I) (X=O, S, NH, NR3 (R3=C1-12-alkyl) or O-(CH2)n (where n=1-16 approximately); R2=C2-20 straight-chain or branched alkyl, monocyclic or polycyclic cycloalkyl or heterocycloalkyl, or alkylaryl hydrocarbon chain, comprising an olefinic double bond in the chain, or at the end of the chain in the case of alkyl or alkylaryl, or an exocyclic or endocyclic olefinic double bond in the case of monocyclic or polycyclic cycloalkyl or heterocycloalkyl; and R1=H or C1-5-alkyl), is reacted at 10 DEG -60 DEG C. with at least one oxidising compound (hydrogen peroxide) in the presence of at least one catalyst (alkali metal molybdates and tungstates) and in the presence of at least one phase transfer agent and when R2=polycyclic cycloalkyl or hetercycloalkyl, an organic peracid or hydrogen peroxide in the presence of at least one heteropolyacid. To open the epoxide function, the epoxide obtained is reacted with a compound chosen from strong inorganic acids, boron trifluoride etherate complexes, acid salts in the presence of the corresponding acid, halides of trialkylsilanes or trialkoxysilanes, and ketones in the presence of cationic resins.
