 EXHIBIT 10.1 

TRANSITION AGREEMENT AND GENERAL RELEASE AND WAIVER OF CLAIMS 

This Transition Agreement and General Release and Waiver of Claims (hereafter “Agreement”) is entered into by and between PQ
Corporation, a Pennsylvania corporation (the “Company”‘), and Michael Crews (the “Mr. Crews”). 
 In
consideration of the mutual promises and covenants contained herein, including but not limited to the benefits set forth in Schedule A, a copy of which is attached and incorporated by reference herein, and the Severance Agreement dated as of
August 31, 2017 (the “Severance Agreement”), and other good and valuable consideration the receipt of which hereby is acknowledged, the parties agree as follows: 

(1)    Separation from Employment. The parties have mutually agreed that, as a result of the downsizing of the Company,
Mr. Crews’ employment will end as of September 30, 2021 (the “Separation Date”). Effective on his Separation Date, Mr. Crews’ employment with the Company will cease subject to the terms and conditions hereinafter
set forth. Between the date on which Mr. Crews signs this Agreement and the Separation Date, Mr. Crews will continue to report to work on a regular basis and perform his regular duties, unless the Company determines that Mr. Crews no
longer has to report on a full-time or regular basis, in which case the Company will continue to pay Mr. Crews his regular salary and maintain his benefits through the Separation Date. Between the date of this Agreement and the Separation Date,
Mr. Crews is entitled to take all accrued but unused vacation time and/or paid time off. During that time period, the Company will also continue to pay Mr. Crews his regular salary and maintain his regular benefits. The Company will also
pay Mr. Crews for all properly reported and reimbursable expenses incurred prior to the Separation date. 
 (2)    Release and
Waiver of Claims. Mr. Crews, for himself and his family, heirs, executors, administrators, legal representatives, and their respective successors and assigns (the “Related Parties”), hereby releases and forever discharges
the Company, and all of its parents (including but not limited to PQ Group Holdings, Inc.), affiliates, subsidiaries, divisions and joint ventures, and their respective officers, directors, employees, agents, parents, stockholders, representatives,
employee benefit plans and their successors and assigns (collectively, “Company Entity” or “Company Entities”), from all rights, claims, demands, suits, causes of action of any kind or nature whatsoever, known or
unknown, in law or in equity Mr. Crews ever had, has or may have or which the Related Parties may have, arising at any time on or before the date hereof, based on or arising out of Mr. Crews’ dealings with any Company Entity,
including but not limited to any claims arising out of Mr. Crews’ employment with any Company Entity or the decision to end that employment on the Separation Date, including without limitation any claims under the Severance Agreement, or
based on any services provided to any Company Entity by Mr. Crews other than pursuant to an employment relationship with any Company Entity. This includes a release of any and all rights, claims or demands Mr. Crews may have, whether known
or unknown, under the Age Discrimination in Employment Act (“ADEA”), which prohibits age discrimination in employment; Title VII of the Civil Rights Act of 1964, which prohibits discrimination in













 
employment based on race, color, national origin, religion or sex; the Equal Pay Act, which prohibits paying men and women unequal pay for equal work; or under any other federal, state or local
laws or regulations regarding employment discrimination or termination of employment. This also includes a release by Mr. Crews of any claims for wrongful discharge or discrimination under any statute, rule, regulation or under the common law,
including, without limitation, the Sarbanes-Oxley Act. 
 (3)    Rights Not Released or Waived. This release is intended to be a
general release and excludes only those claims under any statute or common law that Mr. Crews is legally barred from releasing. Mr. Crews understands that the release does not include and the parties hereto expressly reserve: (i) any
claim that cannot be released or waived as a matter of law; (ii) any claim for or right to vested benefits in accordance with the Company’s employee benefit plans and equity arrangements, including but not limited to any pension or
retirement account benefits, but specifically excluding, among other plans, any other severance plan or policy; (iii) any right to enforce any term of this Agreement and any surviving provisions of the Severance Agreement; (iv) any claims
based on acts or events occurring after Mr. Crews signs this Agreement, except for claims arising from Mr. Crews’ employment or termination of employment with Company, up to and through the date Mr. Crews signs this Agreement;
(v) any claims with respect to indemnification or coverage under directors’ and officers’ liability insurance or any challenge to the validity of the Agreement; (vi) the right to file a charge or complaint with, or provide
testimony, assistance or participation in, any investigation, proceeding or hearing conducted by any federal, state or local governmental agency, including but not limited to the Equal Employment Opportunity Commission (“EEOC”) and
to report violations of any law administered by the Occupational Safety and Health Administration (“OSHA”), or to provide documents and make other disclosures protected under the whistleblower provisions of state or federal law or
regulation (including but not limited to the Security and Exchange Act); or (vii) the right to receive any financial awards from OSHA or the SEC for reporting possible violations of federal law or regulation in cases where the law prohibits
employees from waiving their rights to receive such payments. 
 (4)    Section 409A. (a) Mr. Crews understands that
because Mr. Crews is a “specified employee” under Section 409A of the Internal Revenue Code (“IRC”), he will incur adverse tax consequences if his separation benefits which are not otherwise excluded under 409A begin
within six months of the Separation Date. Because of those tax consequences, Mr. Crews is hereby informed to consult with an attorney of his choice (and at his expense). 

(b)    For purposes of this Agreement, each payment is intended to be excepted from Section 409A to the maximum
extent provided as follows: (i) each payment made within the applicable 24 month period specified in Treas. Reg. § 1.409A-1(b)(4) is intended to be excepted under the short-term deferral exception;
(ii) post-termination medical benefits are intended to be excepted under the medical benefits exceptions as specified in Treas. Reg. § 1.409A-l(b)(9)(v)(B); and (iii) to the extent payments are
made as a result of an involuntary separation, each payment that is not otherwise excepted under the short-term deferral exception or medical benefits exception is intended to be excepted under the involuntary pay exception as specified in Treas.
Reg. § 1.409A-l(b)(9)(iii). Mr. Crews shall have no right to designate the date of any payment under this Agreement. Except as otherwise permitted under Section 409A, no payment hereunder shall
be accelerated or deferred unless such acceleration or deferral would not result in additional tax or interest pursuant to Section 409A.

this Agreement, except as provided under Article III of the Severance Agreement. 
 (c)    If any administrative agency or court assumes

connection with such claim or cause of action, including but not limited to charges filed with the EEOC.
