Case Study

Potassium octoate as a novel catalyst for transesterification of flexible polyurethane foams with diethylene glycol

Molero, Carolina, Antonio de Lucas, and Juan F. Rodriguez. Polymer degradation and stability 94.4 (2009): 533-539.

Polyurethane foams are not only disposed of at the end of their use, but also as waste during block manufacturing. Flexible polyurethane foams can be advantageously processed by two-phase glycolysis in order to recover their constituent polyols with improved quality compared to single-phase processes. Glycolysis includes transesterification reactions, which are traditionally catalyzed by alkanolamines, titanium compounds and acetates. In this work, novel catalysts based on alkali metal, alkaline earth metal and transition metal octoates such as potassium octoate were evaluated for their performance. The carboxylates showed different catalytic activities depending on their basicity and coordination ability. The reaction mechanism of polyurethane glycolysis in the presence of the investigated carboxylate catalysts was also proposed. The mechanism involves several steps, including the formation of metal alkoxides, the coordinated insertion of alkoxides into carbamate groups and the transfer from the recovered polyols to ethylene glycol. Among the investigated octoates, lithium octoate and stannous octoate showed significant catalytic activity. They recovered polyols of the highest quality and with the highest decomposition rates.
The top liquid phase consists mainly of PU recycled polyols, contaminated by a small amount of the bottom liquid layer. This product contains DEG used in excess and low-weight compounds derived from the polyurethane components. As an example, the figure shows the GPC chromatogram of an industrial starting polyether polyol for foam synthesis and the upper phase reaction product obtained after 120 minutes of reaction with potassium octoate as catalyst. The main product in the upper phase corresponds to the starting polyol, which is completely recovered with similar properties to the original polyol. This is obtained without relevant molecular weight losses and with similar polydispersities (Mw=3580, P=1.05; Mw recovered product == 3330, P=1.07). This fact indicates that the polymer is recovered in the state in which it is used in the polyurethane foam synthesis. Due to the complete degradation of the polyurethane chains, higher molecular weight products are not present. The bottom liquid phase is formed by low-weight products: mainly DEG used in excess and aromatic by-products originating from the starting isocyanate.

Preparation of starch-filled polyisocyanurate foam catalyzed by potassium octoate

Goonack, Sirima. (2019).

In reducing the apparent density and improving the fire resistance of polyisocyanurate (PIR) foams. PIR foams were prepared using zinc ammine complex and potassium octoate as catalysts for gelation/foaming and trimerization reactions, respectively. Three types of starch, namely glutinous rice flour, rice flour, and mung bean starch, were used as additives for PIR foams. The properties of starch-modified PIR foams included reaction time (emulsification time, gel time, rise time, and surface dry time), polyisocyanurate/polyurethane (PIR/PUR) ratio, isocyanate conversion%, apparent density, compression properties, morphology, and fire performance behavior. These properties were compared with PIR foams without starch. The experimental results showed that the addition of starch to PIR foams reduced the apparent density and improved the fire resistance compared with PIR foams without starch. Starch-modified PIR foams exhibited self-extinguishing properties.
The processing of PIR foams was as follows: In the first step, polyols, starches (glutinous rice flour, rice flour and mung bean starch), catalysts (Zn(Amm) and potassium octanoate) and surfactants were mixed manually on a paper cup (750 ml) to obtain a homogeneous mixture. In the second step, PMDI was added to the polyol mixture in the paper cup in the second step of the first step. Finally, the reaction mixture was mixed by a mechanical stirrer at 2000 rpm for 20 seconds. The PIR foams rose freely at room temperature. The reaction times, i.e., emulsification time, gel time, rise time and surface dry time were recorded. The PIR foams were kept at room temperature for 48 h for measurement before studying other properties. The foam samples were cut into a cubic shape of 3.0 × 3.0 × 3.0 cm (length × width × thickness) for the measurement of apparent density, %NCO conversion and PIR/PUR ratio.
