Cationic surfactants comprising an ether link

Номер: US0011724981B2
Автор: Ramanathan S. Lalgudi, Robert J. Cain, Manoj Kumar Valluri
Принадлежит: Battelle Memorial Institute

A cationic surfactant and a method of making the cationic surfactant are described. The method comprises reacting a lipophilic bio-based material having at least one epoxy functional group and a hydrophilic organic compound having at least one cationic functional group and at least one hydroxyl functional group to form a reaction product containing a stable ether linkage connecting the lipophilic bio-based material to the organic compound. At least a portion of the cationic functional groups is neutralized or ion exchanged with an organic acid. Incorporation of the simple organic acid reduces the surfactant's aquatic toxicity and acts as a substrate to encourage co-digestion of the surfactant molecule, making the compound more biodegradable.

Bio-based surfactants have great opportunity for use in a variety of applications such as laundry detergents, industrial cleaners, adjuvants, and oil & gas. Surfactants in these applications can be nonionic, anionic, cationic, or amphoteric. Utilizing high oleic soybean oil as a platform chemical, a variety of surfactants and properties can be produced. While early work focused solely on surfactant use in laundry cleaning and fracking, recent work has expanded functional groups and application evaluations in hard surface cleaning. 1. A composition , comprising one or more compounds selected from candidates 14-32 , 34-48 , and 50-55.2. The composition of comprising at least 0.5 wt % (or at least 1 claim 1 , at least 2 claim 1 , or at least 5 wt %) of one or more compounds selected from candidates 14-32 claim 1 , 34-48 claim 1 , and 50-55.3. The composition of comprising one or more compounds selected from candidates 14-32 claim 1 , 34-48 claim 1 , and 50-55 mixed with SDBS in a weight ratio in the range of 1:10 to 10:1 or 2:1 to 1:2.4. The composition of wherein the one or more compounds is at least 50% biobased carbon claim 1 , or at least 70% biobased carbon.5. The composition of comprising on or more of candidates 25 claim 1 , 32 claim 1 , 43 claim 1 , and 48.6. (canceled)7. A method of washing laundry claim 1 , comprising contacting dirty laundry with the composition of .8. A surfactant compound claim 1 , comprising: a C18 carbon chain moiety comprising a ketone moiety (C═O) at one end of the C18 carbon chain moiety and a OH moiety in the middle of the C18 carbon chain moiety; and further wherein:wherein the surfactant compound comprises a betaine surfactant comprising a quarternary ammonium; orwherein the surfactant compound comprises a hydroxysultaine surfactant comprising a quarternary ammonium; orwherein the surfactant compound comprises an alkoxyamide surfactant; orwherein the surfactant compound comprises a glucoside or polyglucoside surfactant; orwherein ...

Bio-based surfactants

Bio-based surfactants have great opportunity for use in a variety of applications such as laundry detergents, industrial cleaners, adjuvants, and oil & gas. Surfactants in these applications can be nonionic, anionic, cationic, or amphoteric. Utilizing high oleic soybean oil as a platform chemical, a variety of surfactants and properties can be produced. While early work focused solely on surfactant use in laundry cleaning and fracking, recent work has expanded functional groups and application evaluations in hard surface cleaning. The current invention expands on Battelle's high oleic soybean oil (HOSO) surfactant technology. Use of HOSO overcomes the limitations of regular soybean oil and significantly reduces or eliminates undesirable byproducts in most chemistries. However, with use of select reagents, a few candidates were achievable with regular epoxidized soybean oil (ESO). The HOSO surfactant platform offers several key advantages including: a highly water miscible (not typical of C18 surfactants) and water stable surfactant; ability to adjust and vary hydrophilic-lipophilic (HLB) values for stain removal performance; and increased biodegradability without toxic or persistent by-products.

Tensoativos de base biológica

“TENSOATIVOS DE BASE BIOLÓGICA. Os tensoativos de base biológica têm uma grande oportunidade para uso em uma variedade de aplicações, tais como detergentes para lavanderia, produtos de limpeza industrial, adjuvantes e óleo e gás. Os tensoativos nesses pedidos podem ser não iônicos, aniônicos, catiônicos ou anfotéricos. Com o uso de óleo de soja com alto teor oleico como um produto químico de plataforma, uma variedade de tensoativos e propriedades pode ser produzida. Embora os trabalhos anteriores sejam focados individualmente em uso de tensoativo em lavagem de roupas e fraturamento hidráulico, trabalhos recentes expandiram os grupos funcionais e avaliações de aplicação em limpeza de superfícies duras. A presente invenção se expande em tecnologia de tensoativo de óleo de soja com alto teor oleico (HOSO) de Battelle. O uso de HOSO supera as limitações de óleo de soja regular e reduz ou elimina significativamente subprodutos indesejáveis na maioria dos processos químicos. Entretanto, com o uso de reagentes selecionados, alguns candidatos foram obteníveis com óleo de soja epoxidado regular (ESO). A plataforma de tensoativo de HOSO oferece várias vantagens chave, incluindo: um tensoativo altamente miscível em água (não típico de tensoativos C18) e estável em água; habilidade de ajustar e variar valores hidrofílicos-lipofílicos (HLB) para desempenho de remoção de mancha; e biodegradabilidade aumentada sem subprodutos tóxicos ou persistentes.
