摘要

The present disclosure relates to the formation of terephthalate esters of Formula (I) which are formed by the depolymerization of polyethylene terephthalate (PET) or poly(ethylene glycol-co-1,4-cyclohexanedimethanol terephthalate). The depolymerization process comprises contacting polyethylene terephthalate or poly(ethylene glycol-co-1,4-cyclohexanedimethanol terephthalate) with a solvent for swelling the polyester, an alcoholic solvent, and a sub-stoichiometric amount of an alkoxide. In the Formula (I) R 1 and R 2 are independently selected from the group consisting of hydrogen, C1-C6 alkyl, C1-C6 haloalkyl, C1-C6 hydroxyalkyl, optionally substituted C3-C8 cycloalkyl, optionally substituted (C1-C6 alkyl)(C3-C8 cycloalkyl), optionally substituted aryl, and optionally substituted (C1-C6 alkyl)(aryl); provided that one of R 1 or R 2 is not hydrogen.

数据来源、服务说明与合规信息

数据来源

LaoBiz.com 是面向全球企业的老挝商业信息与市场研究平台，帮助企业更高效地了解老挝市场、发现商业机会并寻找潜在合作伙伴。平台商业信息主要来源于老挝政府主管机关维护的官方公开登记系统，包括工贸部 NED（企业注册）、BNED（经营许可）、eBRS（工商登记）与财政部 TaxRIS（税务登记），以及知识产权等相关官方公开渠道。LaoBiz.com 不创造或修改企业登记事实，而是在上述官方公开信息基础上，通过数据整理、标准化处理、多语言转换、行业分类和智能检索技术，让分散的信息更加易于查询、理解和应用。平台持续关注官方公开数据变化，并通过数据同步机制帮助用户获取企业最新公开状态。

LaoBiz.com is a Laos business-information and market-research platform for global companies—helping users understand the Lao market, discover opportunities and find potential partners more efficiently. Commercial records are drawn mainly from official public registry systems maintained by Lao competent authorities—including MoIC’s NED (enterprise registration), BNED (business licences) and eBRS (business registration), MoF’s TaxRIS (tax registration), and related official public channels such as intellectual-property filings. LaoBiz.com does not create or alter registry facts; on top of those official public records we organise, standardise, translate, classify by industry and index for search so fragmented filings are easier to find, understand and use. We continuously watch official public-data changes and offer sync tools so users can check an enterprise’s latest public status.
