Estimating the term…
The present invention relates to a process for the preparation of an ester from a polyol which is solid at 25° C. and a carboxylic acid component which contains at least 50 wt. % of at least one mono- or polyunsaturated aliphatic carboxylic acid, based on the total weight of the carboxylic acid component, in a reactor under reduced pressure. The invention also provides a device, a process for the preparation of a thermoplastic composition comprising the ester prepared according to the invention, a process for the production of a shaped article comprising the ester according to the invention or the thermoplastic composition according to the invention, a process for the production of a packed product, a process for the production of an at least partly coated object, and uses of the esters according to the invention as an additive in various compositions.
A process for the preparation of an ester, at least based on
The process according to one of the preceding claims, wherein
The process according to one of the preceding claims, wherein a ratio of unsaturated C16-carboxylic acids to unsaturated C18-carboxylic acids of from 1:5 to 1:20 is present in the carboxylic acid component.
The process according to one of the preceding claims, wherein the carboxylic acid component comprises an amount of less than 25 wt. %, preferably less than 20 wt. %, or less than 13 wt. %, of saturated carboxylic acids.
The process according to one of the preceding claims, wherein the catalyst is employed in an amount of 0.01-5.0 wt. %, based on the total weight of the sum of the alcohol components and carboxylic acid components.
The process according to one of the preceding claims, wherein the carboxylic acid component has been obtained from beef tallow.
The process according to one of the preceding claims, wherein a catalyst which comprises one or more compounds chosen from the group consisting of divalent tin compounds, p-toluenesulphonic acid, methanesulphonic acid, sulphuric acid, hypophosphorous acid, in particular tin oxalate, tin oxide, tin octoate, is employed as an additive.
The process according to one of the preceding claims, wherein the reaction is carried out at a temperature in a range of from 150 to 250° C.
The process according to one of the preceding claims, wherein the ester has at least one of the following features:
A device comprising as device units connected by fluid-conducting means
A formulation obtainable by a process according to one of claims 27 to 30.
