Embodiment Construction

[0018] Many of the polyols used in the synthesis of polyurethanes are synthetic. Accordingly, there is a growing interest in generating natural oil polyols from bio-based sources to minimize dependence on petroleum products and reduce carbon footprint. Typically, natural oil polyols (NOPs) are derived from vegetable oils such as soybean oil, rapeseed oil, and palm oil, among others. These vegetable oils are derived down to their respective C 12 to C 22 organic saturated and unsaturated acids, which are used as initiators to generate NOP. However, the chemistry used to synthesize NOPs produces species with low molecular weight and / or secondary hydroxyl groups. Furthermore, sources of the required vegetable oils can be limited and / or expensive. Therefore, it may be desirable to use feedstock derived from recycled materials. According to the present disclosure, such recovered materials may include used oils, such as animal oils, cooking oils, frying oils, and waste oils. Th...

Abstract

Disclosed embodiments include an open cell, molded polyurethane foam comprising the reaction product of a reaction mixture comprising: an isocyanate mixture; and a polyol formulation, comprising a glycerin-initiated, alkylene-oxide capped natural oil polyol having a molecular weight of between 3,000 and 8,000 and a polydispersity index (PDI) of between approximately 1.5 and 2.5, wherein the PDI is defined as the ratio of the weight-average molecular weight, Mw, to the number-average molecular weight, Mn.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and the benefit of: U.S. Provisional Application Serial No. 61 / 820571, filed May 7, 2013, entitled "NATURALOILPOLYOLSDERIVEDFROMPOST-CONSUMERRECYCLEOILS"; and filed March 24, 2014 US Provisional Application Serial No. 61 / 969543, entitled "NATURALOILPOLYOLSDERIVEDFROMPOSTCONSUMERRECYCLEOILS"; both provisional patent applications are hereby incorporated by reference in their entirety for all purposes. Background technique [0003] The present disclosure generally relates to the production of polyols from recovered waste oils and their use to produce foam products. [0004] Polyurethanes are a general class of polymers in which organic repeating units are linked by urethane and urea linkages. Polyurethanes are generally prepared by a reaction in which a polyol having two or more hydroxyl groups is reacted with an isocyanate having two or more functional isocyanate groups. Hydroxyl and i...
