A method for performing a flying grade switch in an ester production process, which preferably is operated in semi-continuous mode, maximizes plant equipment productivity while minimizing product cross-contamination. Mixed ester products of the process containing a C-Calkyl or isodecyl benzoate together with a higher molecular weight di-alkyl phthalate or cyclohexanoate, bring performance advantages such as improved permanence in plasticized PVC articles or improved processability in manufacturing these articles.

Ester production

Esters of cyclohexane polycarboxylic acids are used as plasticisers for polyvinyl chloride to enable products with comparable mechanical properties to be obtained using less polyvinyl chloride. Use of these esters also produces formulations with increased stability to ultra-violet light, improved low temperature properties, lower viscosity and improved processability as well as reduced smoke on burning. The esters of cyclohexane polycarboxylic acids may be used alone or in admixture with other plasticisers when the esters of cyclohexane polycarboxylic acids may act as viscosity depressants. Fast fusing plasticisers may also be included. The formulations and processes of making these formulations are particularly useful in the production of a range of goods from semi-rigid to highly flexible materials and are particularly useful in the production of medical materials, toys, and food contact articles.

Plasticised polyvinyl chloride and processes for making the same

Provided are compounds of the formula: wherein m=0-3 and n=0-3, andRrepresents CHwherein x=0 to 4 or cyclohexane; Rrepresents H, a C-Calkyl group at any of the ortho-, meta- or para-positions, a residue including heteroatoms chosen from O, N, and S, or mixtures thereof; and Rand Rrepresent hydrocarbon residues of OXO-C-Calcohols which are different isomers of equal carbon number or different in carbon number. Also provided are processes for making the compounds and plasticized polymer compositions containing said compounds.

Plasticized polyvinyl chloride

A release agent for use in imaging systems having hot a fuser roller wherein the release agent is a hydrocarbon.

Release agent and uses for same

An industrial formulation-fluid system comprising one or more organic volatile formulation-fluids including a fluid F being a compound containing either an oxygen-containing or nitrogen-containing functional group and being substantially free from unsaturated carbon-carbon bonds or aromatic groups. Fluid F is selected from the group consisting of: carbonates, acetates, dioxalanes, pivalates, isobutyrates, pentanoates, propionates, hexanoates, nonanoates, nitriles and mixtures of any two or more thereof, such that fluid F exhibits a reduction in ozone formation in an amount of at least 10% less than that of the formulation-fluid system without fluid F. Also, fluid F has an ozone formation potential (OFP) (in accordance with the Absolute MIR scale in units of g. ozone/g. fluid F) of &lE;1.5.

Environmentally preferred fluids and fluid blends

The invention concerns fluids that have a low reactivity with respect to ozone formation, blends thereof, and the replacement of conventional industrial solvents with said fluid or fluid blends in order to reduce tropospheric ozone formation.
