博士后�

具体工作地点:

法国普瓦捷环境与材料研究所

薪金:

待议

项目简介：用于设计可再生表面活性剂的低聚糖合成。
博士后职位简介：这个为期一年的博士后职位由 IC2MP 和 SYENSQO 合作提供，旨在开发一种催化
反应，从天然多糖中生产生物基表面活性剂，用于家庭个人护理中的各种应用。在先前工作的基
础上，IC2MP 的策略将包括多糖的催化控制解聚，以获得具有所需分子量的寡糖及其进一步的功
能化。将优先使用工业催化剂。催化反应将在高压釜中进行，并通过尺寸排阻色谱、NMR 和质谱
法进行监测。在这种情况下，该项目将受益于对 IC2MP 的 PLATINA 分析平台的访问。低聚糖的物
理化学性质及其生物降解性将由 SYENSQO 评估。
工作内容简介：该研究将从文献综述开始，以（1）评估此类反应最有效的工业催化剂，以及
（2）确定与该研究相关的科学和技术挑战。然后，候选人将负责进行第一次催化测试。在初始
阶段，候选人将使用均相酸催化剂。此阶段旨在优化所有反应参数，如压力、温度、浓度、气氛
等。在第二阶段，候选人将专注于使用非均相催化剂。在这些研究任务中，将特别考虑反应选择
性、催化剂消耗、能耗和反应器生产率等性能标准，以指导研究。
IC2MP 和 SYENSQO 之间将定期举行远程或面对面的工作会议，以确保研究项目的顺利进行，并在
必要时调整初始目标。在研究结束时，候选人将制作一份报告提交给 SYENSQO。
期望技能：拥有化学博士学位，候选人应具有应用于精细/有机化学的催化专业知识，并对分析
（SEC、HPLC、NMR、质谱）有浓厚的兴趣。有多糖或糖化学经验者优先。候选人还应该充满好奇
心、保持严谨的态度，并能够作为国际团队的一员工作。

Synthesis of oligosaccharides for the design of renewable surfactants

We are looking for: a one-year postdoc, in collaboration between IC2MP and SYENSQO, which aims to
develop a catalytic reaction to produce bio-based surfactants from natural polysaccharides for various
applications in Home Personal Care.
We count on you for: Building on previous works, the strategy at IC2MP will consist of a catalytic
controlled depolymerization of polysaccharides to obtain oligosaccharides with desired molecular
weights and their further functionalization. Industrial catalysts will be preferentially used. The catalytic
reactions will be carried out in autoclaves and monitored by size-exclusion chromatography, NMR, and
mass spectrometry. In this context, the project will benefit from access to the PLATINA analysis platform
belonging to IC2MP. The physicochemical properties of the oligosaccharides, as well as their
biodegradability, will be evaluated by SYENSQO.
The research will begin with a literature review to (1) assess the most effective industrial catalysts for
this type of reaction and (2) identify the scientific and technological challenges associated with this
research. The candidate will then be in charge of performing the first catalytic tests. Initially,
homogeneous acid catalysts will be used. This phase aims to optimize all reaction parameters such as
pressure, temperature, concentration, atmosphere, etc. In the second phase, the candidate will focus on
using heterogeneous catalysts. Throughout these research tasks, performance criteria such as reaction
selectivity, catalyst consumption, energy consumption, and reactor productivity will be particularly
considered to guide the research.Regular working meetings between IC2MP and SYENSQO, either
remotely or in person, will take place to ensure the smooth progress of the research project and, if
necessary, adjust the initial objectives. At the end of the study, the candidate will produce a report to be
submitted to SYENSQO.
Expected skills: Holder of PhD in chemistry, the candidate should have expertise in catalysis applied to
fine/organic chemistry and a strong interest in analysis (SEC, HPLC, NMR, mass spectrometry). Prior
experience in polysaccharide or sugar chemistry would be an advantage. The candidate should also be
curious, rigorous, and able to work as part of an international team.
About us: The Institut de Chimie des Milieux et Matériaux de Poitiers (IC2MP) is a joint research unit
between CNRS and the University of Poitiers, focusing on the design of sustainable reactions/products
(https://ic2mp.labo.univ-poitiers.fr ). It is an interdisciplinary institute working (1) on the development
of eco-efficient technologies (catalysis, bio-solvents, renewable energies, alternative technologies, etc.)
and (2) on the transfer and bioaccumulation of organic molecules in ecosystems. IC2MP has the capacity
to globally integrate the key steps of a chemical compound transformation process by providing
scientific and technological solutions, from design to environmental implications.
Syensqo is a science company developing groundbreaking solutions that enhance the way we live, work,
