Definitions
- the invention relates to a process for producing alkoxylated polyphenols, more specifically alkoxylated lignins.
- Lignin is one of the main components of wood, with cellulose and hemicellulose. Lignin is the most abundant biopolymer on Earth after cellulose. It ensures the rigidity of the wood by interpenetrating the cellulose network while conferring resistance to water and some wood pests.
- lignin can be used for the manufacture of polyurethane foam derivatives. Since lignin is a polyphenol, it has a large number of alcohol functional groups capable of reacting, for example with isocyanates to form the polyurethane derivatives. However, since these alcohol functions are difficult to access within this polyphenol, it is necessary to carry out a propoxylation reaction of these functions beforehand, leading to less congested alcohol functions (further from the polyphenol nucleus), and thereby more accessible.
- the process used by different authors consists first of all in a propoxylation of the lignin by reacting the lignin with the propylene oxide in the presence of a catalyst and then reacting the product obtained with example of isocyanate.
- propylene oxide may be homopolymerized, as mentioned in EP2816052.
- the propoxylated lignin is then mixed with the poly (propylene) glycols, which can not be readily separated from the propoxylated lignin.
- WO2015 / 083092 describes a method in which a solid lignin dispersion is produced in a dispersant, such as polyethylene glycol, di- or tetraethylene glycol or propoxylated glycerol, followed by the addition of a base . Then, propylene oxide is added continuously.
- a dispersant such as polyethylene glycol, di- or tetraethylene glycol or propoxylated glycerol
- the product manufactured is a mixture of propoxylated lignin and dispersant, optionally propoxylated, difficult to separate from the propoxylated lignin. It should also be noted that the reaction times are extremely long.
- the lignin is in solid form. Because of this, it is difficult to engage it in the form of a homogeneous reaction medium. It also tends to generate deposits that can clog different components of an installation, such as for example reactors, pipes, valves, ducts, etc. For this reason, it is also difficult to manipulate on the industrial level.
- the above references disclose suspending lignin in dispersants, which can solubilize at least in part or all the lignin. However, these processes require subsequent separation steps to isolate the propoxylated lignin from the reaction byproducts of the dispersant with the reactants.
- the present invention aims to provide a solution to solve all of the problems mentioned above.
- the invention relates to a method for manufacturing at least one alkoxylated polyphenol comprising the following successive steps:
- the method according to the invention uses as the solvent for the reaction, and in particular polyphenol, the alkoxylated polyphenol.
- the reaction medium is heterogeneous or homogeneous, the most generally heterogeneous.
- the function of the alkoxylated polyphenol as a solvent is to solubilize at least part of the polyphenol and to disperse the part of polyphenol which is not solubilized. As a result, this specific choice of solvent solves the problems related to the separation of the alkoxylated polyphenol obtained.
- the alkoxylated polyphenol obtained by the process according to the invention can be used crude, without any purification other than the elimination of the unreacted alkoxylating agent, and the neutralization of the catalyst.
- the method according to the invention has the advantage of synthesizing the alkoxylated polyphenol in good safety conditions, so that it can be carried out on an industrial scale.
- the operating conditions in terms of temperature and pressure are controlled by the method according to the invention.
- the exothermicity of the reaction is in particular controlled by the presence of a solvent partially solubilizing the polyphenol and diluting the alkoxylating agent.
- the process according to the invention also has the advantage of not restricting the use of alkoxylating agent to propylene oxide alone. Ethylene oxide and / or butylene oxide or mixtures thereof can also be used.
- Step (a): The process according to the invention comprises a step (a) reacting at least one polyphenol, at least one alkoxylating agent, at least one catalyst, in the presence of at least one alkoxylated polyphenol as solvent, the polyphenol / polyphenol alkoxylated mass ratio as a solvent being less than 2, preferably less than or equal to 1.5, more preferably less than or equal to 1, even more preferably less than or equal to 0.5.
- the polyphenols used in the process according to the invention can be chosen from tannins, lignins and natural polyphenols other than tannins and lignins, preferably lignins.
- said polyphenol is a lignin, preferably chosen from kraft lignin, lignosulphonates and organosolv lignins.
- Kraft lignin is derived from the paper making process of the same name.
- kraft lignin is a combination of three phenolic compounds, coumaryl alcohol, coniferyl alcohol and sinapyl alcohol.
- Nndulin AT TM marketed by the company Ingevity
- the kraft lignin marketed by the company Fibria or the lignin marketed by Stora Enso can be used.
- the lignosulphonates differ structurally from the kraft lignin by the addition of sulphonic functions generally salified, which ensures them better solubility in water.
- Examples of lignosulphonates are lignosulphonates of the Borresperse TM, Ultrazine TM, Ufoxane TM or Vanisperse TM type.
- Organosolv lignins are obtained by chemical etching of woody plants, such as cereal straw, using various solvents, such as formic acid or acetic acid.
- various sources of lignins of the organosolv type there is Biolignin TM marketed by the company CIMV or marketed by the company Fibria.
- the polyphenol used is lignin.
- Alkoxylating agents used in the process according to the invention may be chosen from those of formula (I) below:
- R 1 is a hydrogen atom or a C 1 -C 6 alkyl radical.
- R 1 denotes a hydrogen atom or a C 1 -C 2 alkyl radical.
- the alkoxylating agent is particularly preferably selected from ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof, preferably propylene oxide.
- the weight ratio polyphenol / alkoxylating agent is from 0.05 to 2, preferably from 0.1 to 1, more preferably from 0.15 to 0.9, more preferably from 0.15 to 0, 7.
- the catalyst used in the process according to the invention may be chosen from alkali metal hydroxides, sodium or potassium alkoxides, and tertiary amines chosen from trialkylamines and tetramethylguanidine, preferably chosen from among the alkali metal hydroxides.
- the catalyst used in the process according to the invention may be chosen from lithium hydroxide, sodium hydroxide, potassium hydroxide and cesium hydroxide.
- the catalyst represents from 0.01% to 10% by weight, preferably from 1 to 6% by weight relative to the weight of polyphenol.
- Alkoxylated polyphenol used as a solvent for the reaction used in the process according to the invention is a solvent of the reagent, polyphenol. In this sense, it solubilizes at least a portion of the polyphenol.
- the alkoxylated polyphenol obtained at the end of step (a) is the product of the reaction of a polyphenol and an alkoxylating agent.
- the alkoxylated polyphenol as a solvent and the alkoxylated polyphenol manufactured according to the process according to the invention are identical or different, preferably identical.
- said alkoxylated polyphenol as a solvent used in step (a) is obtained by reacting the polyphenol with the same alkoxylating agent as that used in step (a).
- This may be selected from ethylene oxide, propylene oxide, butylene oxide and mixtures thereof in the presence of at least one catalyst.
- said alkoxylated polyphenol as a solvent is obtained according to the process according to the invention.
- a part of the alkoxylated polyphenol produced during an operation can be reused for the operation next.
- a portion of the alkoxylated polyphenol product may serve as a solvent for the reaction, which occurs in alkoxylated polyphenol.
- the very first batch operation or the start of the continuous reaction can use an alkoxylated polyphenol as a solvent produced by another method than that of the invention. It can be obtained by any method known to those skilled in the art, such as that described in the thesis entitled “Lignin-based Polyurethanes: Characterization, Synthesis and Applications” Borges Cateto, (2008).
