Definitions
- the present invention relates to a process for the purification of norbornene by distillation.
- French patent application FR-A-2 438 639 describes a process for the manufacture of norbornene from the products of the norbornene synthesis reaction between DCPD or CPD and ethylene: - in accordance with a first embodiment (illustrated by Figure 1 of FR-A-2 438 639), the crude synthesis is introduced into a first distillation column, the top product of which, after condensation, is reacted at 70 ° C. with an average residence time of one hour to dim the CPD to DCPD, then reintroduced into the column.
- the mixture of products which falls in the column bottom at 105 ° C is introduced into a second distillation column, the product containing norbornene being vaporized and all the heavy compounds being drawn off as the column bottom product; in accordance with a second embodiment (illustrated by FIG. 2 of FR-A-2 438 639), the crude oil is introduced into a first distillation column, where, at 112 ° C. and with an average residence time d About 30 hours, a large part of the product containing norbornene is vaporized, the heavy components being withdrawn as column bottom products and containing norbornene in a very large proportion.
- the top product is brought into a second distillation column, where one obtains at the top, norbornene still containing fractions of dicyclopentadiene, and, at the bottom, high-purity norbornene.
- the disadvantage of the two systems described above, without topping, lies in the presence of light impurities, such as isoprene, the origin of which is DCPD from O 99/28279
- the monomerization of DCPD is not immediate, so that the composition is also influenced by the residence times of the products in the columns.
- the object of the present invention is to propose a process for the purification of norbornene by distillation which no longer has any of the drawbacks of the processes of the prior art and which makes it possible to operate industrially to obtain a norbornene of satisfactory quality.
- this object is achieved, in other words, a regular quality of norbornene as free as possible of heavy and light residuals can be obtained, without excessive loss of product, by a process involving three successive distillation columns. .
- the process according to the present invention for the purification of norbornene obtained by the reaction of dicyclopentadiene or cyclopentadiene and ethylene, the crude reaction mixture containing: light impurities, the boiling temperatures of which are lower than that of norbornene; - medium-heavy impurities, the temperatures of which are between that of norbornene and that of ethyl norbornene; and heavy impurities, the temperatures of which are higher than those of ethyl norbornene, the latter being moreover included in said heavy impurities, is characterized in that a first distillation of the crude reaction mixture is carried out in a tailing column (Cl), eliminating part of the heavy impurities and part of the medium-heavy impurities; then a second distillation of the crude mixture thus hulled in a topping column (C2), removing the light impurities; and then a third distillation of the mixture thus topped in a tailing column (C3), eliminating the rest of the heavy and semi-heavy
- the bottom stream of the second tailing column (C3) is recycled to the inlet of the first tailing column (C1).
- this column fitted with filling elements, is to eliminate part of the heavy and medium heavy; it is fed by a stream (1) of raw norbornene, which titers approximately 85 to 98% depending on the quality of the DCPD or of the CPD / DCPD reacted and the operating conditions of the synthesis (molar ratio, flow rate).
- the impurities which are listed in Tables 1 and 2 below, are classified into: light impurities representing 0.1 - 1%; - medium-heavy impurities representing 0.1 - 1%; and - heavy impurities representing 1 - 15% (for 100% in total).
- This column (Cl) works at atmospheric pressure, with a bottom temperature of 100 to 160 ° C and a head temperature, from 95 to 110 o C.
- This column (Cl) makes it possible to eliminate, for example, in stream (3), approximately 25 - 75% of the medium-heavy methylnorbornenes, which are due to methylcyclopentadiene, classic and inevitable impurity of the CPD, and approximately 95-99% heavy (recombination of the CPD in DCPD).
- the purpose of the column (C2), filled with filling elements, is to eliminate the majority of the light ones.
- This column works at atmospheric pressure, with a bottom temperature of 95 - 100 "C and a head temperature of 94 - 100 ° C.
- a flux (4) is obtained having the following composition (for 100%): 2 - 10% of light;
- the flow (6) leaving the reservoir (R) downstream of the column (C2), has the following composition (for 100%): 0 - 0.1% of light;
- the desired flux (7) is obtained, having the following composition (for 100%): 0 - 0.1% of light;
- the process according to the present invention makes it possible to obtain a better quality of norbornene than the previous processes, with the additional advantage that this higher purity is obtained with little loss.
- Example 1 illustrates the present invention without, however, limiting its scope. In these Examples, the percentages are also given by weight.
