Abstract: PURPOSE: A VPI(Virtual Path Identifier) extension method for an ABR(Available Bit Rate) multipoint-to-point connection in an ATM network is provided to solve a problem of congestion control balance in an existing VC merging technique and the problem that many VPI/VCI tables are required in an existing VP merging technique. CONSTITUTION: The fourth exchange receives ATM cells, having an identical VPI value but different VCI values, from different sources through an ATM network(S1). The fourth exchange checks the MSB(Most Significant Bit) values of the VPI fields of the ATM cells and judges the connection type of the ATM cells(S2). In case that the MSB values of the VPI fields of the ATM cells is "0" which means that the connection type is a multipoint-to-point connection, the fourth exchange extracts the VPI value from each VPI field, extends each VPI value into a 16-bit value, and inserts each extended VPI value into each VCI field(S3). Then the fourth exchange extracts a VCI value from each VCI field, converts each VCI value into a 11-bit value using the multipoint-to-point VCI conversion information of the multipoint-to-point connection field of a VPI/VCI table, and inserts each converted VCI value into each VPI field(S4). Then the fourth exchange classifies the sources through the VCI values in the their respective VPI fields, executes cell interleaving at a merging point, and transmits the ATM cells to an identical destination source(S5).

Abstract: The invention relates to an apparatus for the production of butylacetate by esterification of acetic acid with butanol in the presence of a solid acidic catalyst in which distillatory separation of components runs simultaneously with esterification. Thus, acetic acid and butanol are introduced in defined amounts and in the molar ratio 1:1 to 1:10 into a system, in which the reaction and the distillatory separation proceeds in three zones. The reaction together with distillatory separation of the components with different boiling points run in the reaction zone, while only distillation takes place in lower and upper separation zones. A volatile mixture is separated in the upper separation zone, from which, after being cooled at 5 to 80° C., water and organic phases are separated, the latest being refluxed into the system. The ratio of the feed amount to the organic phase reflux amount is 1:1 to 1:20, the reflux amount representing 60 to 100% of the whole amount of the organic phase. Butylacetate is separated as a high boiling bottoms product. The invention relates also to the production of isobutylacetate by esterification of acetic acid with isobutyl alcohol in the presence of a solid acidic catalyst in which separation of components by distillation runs simultaneously with esterification.
